<br />'. <br /> <br /> <br />Cold Brook, Chatfield, Cherry Creek, and Salt Creek #18. Evacuation of stored flood water in <br />these projects is scheduled as soon as practicable after each flood event. <br /> <br />(a) North Dakota. Flood, releases from Pipestem Dam will be coordinated with <br />those from the Bureau's Jamestown Dam. The low level gate at Pipestem will be opened when <br />water is flowing over the drop inlet to assist in the improvement of lake water quality. At <br />Bowman-Haley Reservoir, the water quality improvement program calls for releases from the low- <br />level drawdown tube during periods of pronounced lake stratification that typically occur in late <br />winter and again in late summer around July 15. If the local sponsor concurs and winter <br />downstream conditions pennit, water will be evacuated from the lower elevations each year starting <br />in early February. <br /> <br />(b) South Dakota. Cold Brook reservoir inflows up to 1.1 cfs will be released to <br />the Larive Lake Resort when requested to meet their water right. <br /> <br />(c) Colorado. At Chatfield Reservoir, the pool level is expected to fluctuate <br />between elevations 5423 and 5432 ft. MSL at all times except during prolonged periods of drought <br />or excessive run-off. Each year, from May 1 to August 31, the pool level is not expected to fall <br />below elevation 5426.85 ft MSL (20,000 AF) for recreational purposes. Storage of water above <br />elevation 5426.85 to elevation 5432.0 ft. MSL will depend on the availability of free water and/or <br />excessive run-off and/or the desire of the City of Denver to store water. During the Colorado <br />irrigation season, inflows to Cherry Creek Reservoir will be calculated by the Water Control <br />Section and the State Engineer on a daily basis and releases will be balanced on a weekly basis to <br />comply with State water rights. Releases will be made at Cherry Creek Reservoir in Mayor June <br />to flush sediment from around the gates in the intake structure. Flushes will not be scheduled <br />during the December through March period. The flushing schedule utilizes approximately 150 to <br />250 AF of water. At Bear Creek Reservoir, the low level gate will be opened when practical <br />during the June through August period when the lake typically stratifies to assist in the <br />improvement of lake water quality if requested. <br /> <br />(d) Nebraska. At Salt Creek Dam #18, releases of inflow up to a total of 11.57 <br />cfs may be made. Releases up to 3 cfs without proving inflow will be made when required to <br />satisfy downstream water rights. Low level releases will be made when practicable from the Papio <br />projects to allow water to be discharged from lower elevations in an attempt to improve lake water <br />quality . <br />(2) Bureau of Reclamation. As in the past, the Bureau will continue to operate <br />their reservoirs to meet flood control commitments and to coordinate operations with other <br />interests to achieve optimum use of water resources. Generally, all reservoirs will be operated as <br />close to the top of their conservations pools as possible. Pertinent special operating plans are <br />described as follows: Boysen, Canyon Ferry, Clark Canyon, Tiber and Yellowtail Reservoirs <br />require evacuation and refill of joint-use storage for flood control based on mountain run-off inflow <br />forecasts. <br /> <br />16 <br /> <br />
