(1) Sound signals by means of a whistle. These signals apply at either a single lock or twin locks.
(i) Vessels desiring lockage shall on approaching a lock give the following signals at a distance of not more than one mile from the lock;
(a) If a single lockage only is required: One long blast of the whistle followed by one short blast.
(b) If a double lockage is required: One long blast of the whistle followed by two short blasts.
(ii) When the lock is ready for entrance, the lock will give the following signals:
(a) One long blast of the whistle indicates permission to enter the lock chamber in the case of a single lock or to enter the landward chamber in the case of twin locks.
(b) Two long blasts of the whistle indicates permission to enter the riverward chamber in the case of twin locks.
(iii) Permission to leave the locks will be indicated by the following signals given by the lock:
(a) One short blast of the whistle indicates permission to leave the lock chamber in the case of a single lock or to leave the landward chamber in the case of twin locks.
(b) Two short blasts of the whistle indicates permission to leave the riverward chamber in the case of twin locks.
(iv) Four or more short blasts of the lock whistle delivered in rapid succession will be used as a means of attracting attention, to indicate caution, and to signal danger. This signal will be used to attract the attention of the captain and crews of vessels using or approaching the lock or navigating in its vicinity and to indicate that something unusual involving danger or requiring special caution is happening or is about to take place. When this signal is given by the lock, the captains and crews of vessels in the vicinity shall immediately become on the alert to determine the reason for the signal and shall take the necessary steps to cope with the situation.
(2) Lock signal lights. At locks where density of traffic or other local conditions make it advisable, the sound signals from the lock will be supplemented by signal lights. Flashing lights (showing a one-second flash followed by a two-second eclipse) will be located on or near each end of the land wall to control use of a single lock or of the landward lock of double locks. In addition, at double locks, interrupted flashing lights (showing a one-second flash, a one-second eclipse and a one-second flash, followed by a three-second eclipse) will be located on or near each end of the intermediate wall to control use of the riverward lock. Navigation will be governed as follows:
(i) Red light. Lock cannot be made ready immediately. Vessel shall stand clear.
(ii) Amber light. Lock is being made ready. Vessel may approach but under full control.
(iii) Green light. Lock is ready for entrance.
(iv) Green and amber. Lock is ready for entrance but gates cannot be recessed completely. Vessel may enter under full control and with extreme caution.
(3) Radio communications. VHF-FM radios, operating in the FCC authorized Maritime Band, have been installed at all operational locks (except those on the Kentucky River and Lock 3, Green River). Radio contact may be made by any vessel desiring passage. Commercial tows are especially requested to make contact at least one half hour before arrival in order that the pilot may be informed of current river and traffic conditions that may affect the safe passage of his tow.
(4) All locks monitor 156.8 MHz (Ch. 16) and 156.65 MHz (Ch. 13) and can work 156.65 MHz (Ch. 13) and 156.7 MHz (Ch. 14) Ch. 16 is the authorized call, reply and distress frequency, and locks are not permitted to work on this frequency except in an emergency involving the risk of immediate loss of life or property. Vessels may call and work Ch. 13, without switching, but are cautioned that vessel to lock traffic must not interrupt or delay Bridge to Bridge traffic which has priority at all times.
(k) Rafts. Rafts to be locked through shall be moored in such manner as not to obstruct the entrance of the lock, and if to be locked in sections, shall be brought to the lock as directed by the lockmaster. After passing the lock the sections shall be reassembled at such distance beyond the lock as not to interfere with other vessels.
(l) Entrance to and exit from locks. In case two or more boats or tows are to enter for the same lockage, their order of entry shall be determined by the lockmaster. Except as directed by the lockmaster, no boat shall pass another in the lock. In no case will boats be permitted to enter or leave the locks until directed to do so by the lockmaster. The sides of all craft passing through any lock shall be free from projections of any kind which might injure the lock walls. All vessels shall be provided with suitable fenders, and shall be used to protect the lock and guide walls until it has cleared the lock and guide walls.
(m) Mooring—(1) At locks. (i) All vessels when in the locks shall be moored as directed by the lockmaster. Vessels shall be moored with bow and stern lines leading in opposite directions to prevent the vessel from “running” in the lock. All vessels will have one additional line available on the head of the tow for emergency use. The pilothouse shall be attended by qualified personnel during the entire locking procedure. When the vessel is securely moored, the pilot shall not cause movement of the propellers except in emergency or unless directed by the lockmaster. Tying to lock ladders is strictly prohibited.
(ii) Mooring of unattended or nonpropelled vessels or small craft at the upper or lower channel approaches will not be permitted within 1200 feet of the lock.
(2) Outside of locks. (i) No vessel or other craft shall regularly or permanently moor in any reach of a navigation channel. The approximate centerline of such channels are marked as the sailing line on Corps of Engineers' navigation charts. Nor shall any floating craft, except in an emergency, moor in any narrow or hazardous section of the waterway. Furthermore, all vessels or other craft are prohibited from regularly or permanently mooring in any section of navigable waterways which are congested with commercial facilities or traffic unless it is moored at facilities approved by the Secretary of the Army or his authorized representative. The limits of the congested areas shall be marked on Corps of Engineers' navigation charts. However, the District Engineer may authorize in writing exceptions to any of the above if, in his judgment, such mooring would not adversely affect navigation and anchorage.
(ii) No vessel or other craft shall be moored to railroad tracks, to riverbanks in the vicinity of railroad tracks when such mooring threatens the safety of equipment using such tracks, to telephone poles or power poles, or to bridges or similar structures used by the public.
(iii) Except in case of great emergency, no vessel or craft shall anchor over revetted banks of the river, and no floating plant other than launches and similar small craft shall land against banks protected by revetment except at regular commercial landings. In all cases, every precaution to avoid damage to the revetment works shall be exercised. The construction of log rafts along mattressed or paved banks or the tying up and landing of log rafts against such banks shall be performed in such a manner as to cause no damage to the mattress work or bank paving. Generally, mattress work extends out into the river 600 feet from the low water line.
(iv) Any vessel utilizing a federally constructed mooring facility (e.g., cells, buoys, anchor rings) at the points designated on the current issue of the Corps' navigation charts shall advise the lockmaster at the nearest lock from that point by the most expeditious means.
(n) Draft of vessels. No vessel shall attempt to enter a lock unless its draft is at least three inches less than the least depth of water over the guard sills, or over the gate sills if there be no guard sills. Information concerning controlling depth over sills can be obtained from the lockmaster at each lock or by inquiry at the office of the district engineer of the district in which the lock is located.
(o) Handling machinery. No one but employees of the United States shall move any lock machinery except as directed by the lockmaster. Tampering or meddling with the machinery or other parts of the lock is strictly forbidden.
(p) Refuse in locks. Placing or discharging refuse of any description into the lock, on lock walls or esplanade, canal or canal bank is prohibited.
(q) Damage to locks or other work. To avoid damage to plant and structures connected with the construction or repair of locks and dams, vessels passing structures in the process of construction or repair shall reduce their speed and navigate with special caution while in the vicinity of such work. The restrictions and admonitions contained in these regulations shall not affect the liability of the owners and operators of floating craft for any damage to locks or other structures caused by the operation of such craft.
(r) Trespass of lock property. Trespass on locks or dams or other U.S. property pertaining to the locks or dams is strictly prohibited except in those areas specifically permitted. Parties committing any injury to the locks or dams or to any part thereof will be responsible therefor. Any person committing a willful injury to any U.S. property will be prosecuted. No fishing will be permitted from lock walls, guide walls, or guard walls of any lock or from any dam, except in areas designated and posted by the responsible District Engineer as fishing areas. Personnel from commercial and recreational craft will be allowed on the lock structure for legitimate business reasons; e.g., crew changes, emergency phone calls, etc.
(s) Restricted areas at locks and dams. All waters immediately above and below each dam, as posted by the respective District Engineers, are hereby designated as restricted areas. No vessel or other floating craft shall enter any such restricted area at any time. The limits of the restricted areas at each dam will be determined by the responsible District Engineer and market by signs and/or flashing red lights installed in conspicuous and appropriate places.
(t) [Reserved]
(u) Operations during high water and floods in designated vulnerable areas. Vessels operating on these waters during periods when river stages exceed the level of “ordinary high water,” as designated on Corps of Engineers' navigation charts, shall exercise reasonable care to minimize the effects of their bow waves and propeller washes on river banks; submerged or partially submerged structures or habitations; terrestrial growth such as trees and bushes; and man-made amenities that may be present. Vessels shall operate carefully when passing close to levees and other flood protection works, and shall observe minimum distances from banks which may be prescribed from time to time in Notices to Navigation Interests. Pilots should exercise particular care not to direct propeller wash at river banks, levees, revetments, structures or other appurtenances subject to damage from wave action.
(v) Navigation lights for use at all locks and dams except on the Kentucky River and Lock 3, Green River. (1) At locks at all fixed dams and at locks at all movable dams when the dams are up so that there is no navigable pass through the dam, the following navigation lights will be displayed during hours of darkness:
(i) Three green lights visible through an arc of 360° arranged in a vertical line on the upstream end of the river (guard) wall unless the intermediate wall extends farther upstream. In the latter case, the lights will be placed on the upstream end of the intermediate wall.
(ii) Two green lights visible through an arc of 360° arranged in a vertical line on the downstream end of the river (guard) wall unless the intermediate wall extends farther downstream. In the latter case, the lights will be placed on the downstream end of the intermediate wall.
(iii) A single red light, visible through an arc of 360° on each end (upstream and downstream) of the land (guide) wall.
(2) At movable dams when the dam has been lowered or partly lowered so that there is an unobstructed navigable pass through the dam, the navigation lights indicated in the following paragraphs will be displayed during hours of darkness until lock walls and weir piers are awash.
(i) Three red lights visible through an arc of 360° arranged in a vertical line on the upstream end of the river (guard) wall.
(ii) Two red lights visible through an arc of 360° arranged in a vertical line on the downstream end of the river (guard) wall.
(iii) A single red light visible through an arc of 360° on each end (upstream and downstream) of the land (guide) wall.
(3) After lock walls and weir piers are awash they will be marked as prescribed in paragraph (x) of this section.
(4) If one or more bear traps or weirs are open or partially open, and may cause a set in current conditions at the upper approach to the locks, this fact will be indicated by displaying a white circular disk 5 feet in diameter, on or near the light support on the upstream end of the land (guide) wall during the hours of daylight, and will be indicated during hours of darkness by displaying a white (amber) light vertically under and 5 feet below the red light on the upstream end of the land (guide) wall.
(5) At Locks No. 1 and 2, Green River, when the locks are not in operation because of high river stages, a single red light visible through an arc of 360° will be displayed on each end (upstream and downstream) of the lock river (guard) will at which time the lights referred to above will not be visible.
(w) Navigation lights for use at locks and dams on the Kentucky River and Lock 3, Green River. A single red light visible through an arc of 360° shall be displayed during hours of darkness at each end of the river wall or extending guard structures until these structures are awash.
(x) Buoys at movable dams. (1) Whenever the river (guard) wall of the lock and any portion of the dam are awash, and until covered by a depth of water equal to the project depth, the limits of the navigable pass through the dam will be marked by buoys located at the upstream and downstream ends of the river (guard) wall, and by a single buoy over the end or ends of the portion or portions of the dam adjacent to the navigable pass over which project depth is not available. A red nun-type buoy will be used for such structures located on the left-hand side (facing downstream) of the river and a black can-type buoy for such structures located on the right-hand side. Buoys will be lighted, if practicable.
(2) Where powerhouses or other substantial structures projecting considerably above the level of the lock wall are located on the river (guard) wall, a single red light located on top of one of these structures may be used instead of river wall buoys prescribed above until these structures are awash, after which they will be marked by a buoy of appropriate type and color (red nun or black can buoy) until covered by a depth of water equal to the project depth. Buoys will be lighted, if practicable.
(y) Vessels to carry regulations. A copy of these regulations shall be kept at all times on board each vessel regularly engaged in navigating the rivers to which these regulations apply. Copies may be obtained from any lock office or District Engineer's office on request. Masters of such vessels are encouraged to have on board copies of the current edition of appropriate navigation charts.

(a) All previous regulations of the Secretary of War relating to the use of the Mississippi River for the generation of power by the Mississippi River Power Co., including the memorandum of March 24, 1908, approved by the Secretary of War, March 26, 1908, are rescinded, and the following regulations will govern the operation of the dam until further orders:
(b) Excepting as specially provided in this section the normal flow of the river shall be discharged below the dam at all times of day and night.
(c) The Mississippi River Power Co. shall not during the period of navigation raise the level of its pond behind the Keokuk Dam when the natural flow of the Mississippi River is falling or when such natural flow is less than approximately 64,000 cubic feet per second, which corresponds to a normal stage of 6 feet above low water at Keokuk, Iowa, except upon the written permission of the U.S. District Engineer in charge of this locality, such permit to state the period which such ponding may cover and the maximum variation in stage below the dam which may be caused by each ponding.
(d) The granting of permits by the District Engineer shall be governed by the provision of the law authorizing the construction of the dam and its accessories, as follows:
Sec. 2. That the withdrawal of water from the Mississippi River and the discharge of water into the said river, for the purpose of operating the said power stations and appurtenant works, shall be under the direction and control of the Secretary of War, and shall at no time be such as to impede or interfere with the safe and convenient navigation of the said river by means of steamboats or other vessels or by rafts or barges. * * * (33 Stat. 713)
(e) The power company when proposing to raise or lower the pond, either under general authority or special permission, shall give due notice to the District Engineer or his authorized agent of its intention.
(f) The power company shall hold all records relating to operations affecting the river discharge open to the inspection of the District Engineer or his authorized agent.
(g) It shall be the duty of the district engineer or his authorized agent to observe closely and carefully the operations of the power company and to maintain in addition to such as may be maintained by the power company, such river and pool gages as may be advisable, and make from time to time such examinations as may be necessary for determining the effect of the operation of the power dam and accessories on the river channels.
(h) The Department of the Army approves the method of regulating the flow below the Keokuk Dam by estimating the flow 24 hours in advance and maintenance of the stage corresponding to such flow as indicated by the river gage at U.S. Lock (the method employed during 1917). The general rules stated in paragraph (g) of this section are not intended to apply to unavoidable small compensating variations in pond level behind the dam inherent in such method of regulation.

§ 207.340 Reservoirs at headwaters of the Mississippi River; use and administration.
top
(a) Description. These reservoirs include Winnibigoshish, Leech Lake, Pokegama, Sandy Lake, Pine River and Gull Lake.
(b) Penalties. The River and Harbor Act approved August 11, 1888 (25 Stat. 419, 33 U.S.C. 601) includes the following provisions as to the administration of the headwater reservoirs:
And it shall be the duty of the Secretary of War to prescribe such rules and regulations in respect to the use and administration of said reservoirs as, in his judgment, the public interest and necessity may require; which rules and regulations shall be posted in some conspicuous place or places for the information of the public. And any person knowingly and willfully violating such rules and regulations shall be liable to a fine not exceeding five hundred dollars, or imprisonment not exceeding six months, the same to be enforced by prosecution in any district court of the United States within whose territorial jurisdiction such offense may have been committed.
(c) Previous regulations now revoked. In accordance with the above act, the Secretary of War prescribed regulations for the use and administration of the reservoirs at the headwaters of the Mississippi River under date of February 11, 1931, which together with all subsequent amendments are hereby revoked and the following substituted therefor.
(d) Authority of officer in charge of the reservoirs. The accumulation of water in, and discharge of water from the reservoirs, including that from one reservoir to another, shall be under the direction of the U.S. District Engineer, St. Paul, Minnesota, and of his authorized agents subject to the following restrictions and considerations:
(1) Notwithstanding any other provision of this section, the discharge from any reservoir may be varied at any time as required to permit inspection of, or repairs to, the dams, dikes or their appurtenances, or to prevent damage to lands or structures above or below the dams.
(2) Except as provided in paragraph (d)(1) of this section the average annual discharge from the respective reservoirs shall not be reduced below the following values, as nearly as they can practically be maintained:
Winnibigoshish, 150 cubic feet per second.
Leech Lake, 70 cubic feet per second.
Pokegama, 200 cubic feet per second.
Sandy Lake, 80 cubic feet per second.
Pine River, 90 cubic feet per second.
Gull Lake, 30 cubic feet per second.
(3) During the season of navigation on the upper Mississippi River, the volume of water discharged from the reservoirs shall be so regulated by the officer in charge as to maintain as nearly as practicable, until navigation closes, a sufficient stage of water in the navigable reaches of the upper Mississippi and in those of any tributary thereto that may be navigated and on which a reservoir is located.
(4) Surplus waters in storage above the stages listed in paragraph (d)(7) of this section not required for use in the aid of navigation, as provided for in paragraph (d)(3) of this section, may be discharged at such time and at such rates as will result, in the judgment of the District Engineer, in the greatest general benefit or the minimum of injuries to all affected interests.
(5) No discharge other than the minimum specified in paragraph (d)(2) of this section shall be permitted when a reservoir is at or below its minimum stage as set forth in paragraph (d)(7) of this section except such increases of discharge as may specifically be directed by the Chief of Engineers.
(6) The surplus inflow over the minimum discharge set forth in paragraph (d)(2) of this section shall be stored until the limit of capacity or safety of the reservoir is reached, or until such time as water may be discharged in accordance with this section.
(7) So far as practicable, under the requirements of this section, the officer in charge will cause the reservoirs to be maintained above the following minimum stages, referred to zeros of respective Government gauges:
Winnebigoshish 6.0
Leech Lake 0.0
Pokegama 6.0
Sandy Lake 7.0
Pine River 9.0
Gull Lake 5.0
The range of fluctuations in levels in any reservoir in a single calendar year shall be held at a minimum consistent with the requirements of this section and with the inflow of that year. If, through necessity reservoirs are drawn below these stages, minimum stages will be restored at the first practicable opportunity.
(e) Passage of logs and other floating bodies. Logs and other floating bodies may be sluiced or locked through the dams, but prior authority for the sluicing of logs must be obtained from the District Engineer when this operation necessitates a material change in discharge.
(f) Obstructions to flow of water. No person shall place floating bodies in a stream or pond above or below a reservoir dam when, in the opinion of the officer in charge, such act would prevent the necessary flow of water to or from such dam, or in any way injure the dam and its appurtenances, its dikes and embankments; and should floating bodies lying above or below a dam constitute at any time an obstruction or menace as beforesaid, the owners of said floating bodies will be required to remove them immediately.
(g) Trespass. No one shall trespass on any reservoir dam, dike, embankment or upon any property pertaining thereto.

He shall see that all laws, rules and regulations for the use of the lock and lock area are duly complied with, to which end he is authorized to give all necessary orders and directions in accordance therewith, both to employees of the Government and to any and every person within the limits of the lock or lock area, whether navigating the lock or not. No one shall cause any movement of any vessel, boat, or other floating thing in the lock or approaches except by or under the direction of the lockmaster or his assistants.
(4) Signals. (i) Signals from vessels for lockage shall be by whistle, horn or by idling or standing near the ends of the lock guide walls. Signals from the lockmaster shall be by the traffic light and horn and/or by voice with or without electrical amplification. In case of emergency, the lockmaster may signal the vessel by wave of hand or lantern, and the signals thus given shall have the same weight as though given by visual or sound devices at the lock. Vessels must approach the lock with caution and shall not enter or leave the lock until signaled to do so by the lockmaster. The following lockage signals and duration of sound signals are prescribed. A long blast shall be of 4 second duration; a short blast shall be of 1 second duration.
(a) Vessel signals. Inbound vessels at a distance of not more than 4,000 feet from the lock and outbound vessels immediately after crossing under the Lake Shore Drive bridge shall signal for lockage by 2 long and 2 short blasts of a whistle or horn.
(b) Lock signals. (1) When the lock is ready for entrance, the traffic light will show green, and vessels under 500 gross tons shall come ahead under caution and enter the lock; vessels of 500 gross tons or more shall come to a stop along the guide wall, as prescribed in paragraph (b)(5) of this section. Should the traffic light be out of order or be invisible due to thick weather, vessels shall upon 1 long blast of the lock horn approach and moor to the south guide wall or continue into the lock if so directed by the lockmaster.
(2) When the lock is not ready for entrance, the traffic light will show red, and vessels shall not pass beyond the end of the south guide wall: Provided, however, That vessels may approach and moor to said wall if authorized by 1 long blast of the lock horn.
(3) Permission to leave the lock shall be indicated by 1 short blast of the lock horn.
(4) Caution or danger will be indicated by 4 or more flashes of the red traffic light or 4 or more short blasts of the lock horn delivered in rapid succession.

(6) Maximum draft. Vessels drawing within 6 inches of the depth over the sills shall not be permitted lockage except under special permission from the lockmaster.
(7) Precedence at locks. The vessel arriving first at a lock shall be first to lock through; but precedence shall be given to vessels belonging to the United States and to commercial vessels in the order named. Arrival posts or markers may be established ashore above or below the locks. Vessels arriving at or opposite such posts or markers will be considered as having arrived at the locks within the meaning of this paragraph.
(8) Lockage of pleasure boats. The lockage of pleasure boats, house boats or like craft shall be expedited by locking them through with commercial craft (other than barges carrying petroleum products or highly hazardous materials) in order to utilize the capacity of the lock to its maximum. If, after the arrival of such craft, no separate or combined lockage can be accomplished within a reasonable time, not to exceed the time required for three other lockages, then separate lockage shall be made.
(9) Speed of approach and departure. Vessels of 500 gross tons or more when approaching the lock shall navigate at a speed not exceeding 2 miles per hour, and when leaving the lock shall navigate at a speed not exceeding 6 miles per hour. While entering or leaving the lock, the propellers of vessels of 500 gross tons or more shall be operated at slow speed so as not to undermine or injure the concrete paving on the bottom of the lock chamber. Tugs assisting vessels in lockage, and Coast Guard and fire vessels, may navigate at a higher speed when authorized by the lockmaster. Vessels of less than 500 gross tons shall operate at reasonable speed.
(10) Mooring. (i) Vessels shall be moored in the lock or along its approach walls in such manner as may be directed by the lockmaster. Tying to lock ladders, lamp standards, or railings is strictly prohibited. Commercial vessels and tows of 500 gross tons or more shall, in general, have at least one line out when entering the lock and shall be moored in the lock with two bow and two stern lines, which shall lead forward and aft at each end of the vessel or tow. When the gates are closed, commercial vessels shall not be permitted to work their wheels. Said vessels shall have at least two seamen ashore to handle the mooring lines while they are in the lock.
(ii) Mooring lines shall not be cast off until after the lock gates have been opened fully into their recesses, and the signal given to leave the lock. The lines leading aft shall be released first. The lines leading forward shall not be released until the vessel has started to move forward, so as to prevent the vessel from drifting back into the lock gates.
(11) [Reserved]
(12) Unnecessary delay at lock. Masters and pilots must use every precaution to prevent unnecessary delay in entering of leaving the lock. Vessels failing to enter lock with reasonable promptness, when signaled to do so, shall lose their turn.
