Ib) Cherry Creek Reservoir. Colorado Normal Operations. On April 1, 1988, the State of Colorado, through the State Engineer, implemented strict administration of water rights within the Cherry Creek basin. When a senior river call is in effect, the Cherry Creek Reservoir is required to pass inflow through the project, Releases from the project were coordinated by the Hydrology and Water Control Section to comply with downstream river calls as determined by the Colorado State Engineers office, A total of 18 release orders were made during the report period. The releases were made to meet downstream water needs, and to maintain the conservation pool level. Due to scheduled gate maintenance, the annual sediment flushing exercise was not accomplished this year. The flush is scheduled for next year. f .. Ie) Papillion Creek Basin. Nebraska. Minor low-level releases were made at Papillion Creek Reservoir #18, Zorinsky Lake, to lower pool level to facilitate fish habitat. See summary in Section VI. Id) Salt Creek Basin. Nebraska. Minor releases were made from Salt Creek Reservoir #12, Conestoga, during the late summer to facilitate fish habitat as requested by the Nebraska Game and Parks Commission. The Nebraska Game and Parks Commission has scheduled renovation at Salt Creek Reservoirs #2, Olive Creek, and #8, Wagon Train for the coming winter, Releases have been made to lower the lake to the low level gate inverts and the Nebraska Game and Parks has installed siphon tubes at both reservoirs to lower lake levels an additional 5 to 10 feet. Shoreline protection, sediment detention, and possible outlet modification are planned for both projects. Salt Creek Reservoir #18 was lowered 5 feet to facilitate shoreline protection work. The reservoir will be maintained at this level until the work is completed sometime in early spring. Ie) Bowman-Haley. North Dakota. Releases were made from March to May to allow inflows to pass through the reservoir. If) Pipestem. North Dakota. The 1998 snowmelt began with warming temperatures bringing an initial melt of the small amount of snow in the James River on February 22, 1998. On February 27th the NWs issued a spring flood outlook stating that most of the snow in the James River Valley had melted and that no flooding was expected under current conditions. The Omaha District Water Control Office was forecasting a normal runoff year for the first time since the July 1993 rainfall event. . ~ Warm temperatures brought a second round of snowmelt beginning March 2200. The NWs issued a spring flood outlook on March 27th once again stating that no flooding was expected. However the trace amount of remaining snow in the basin brought a surprising amount of inflow into the reservoirs. The factors largely responsible for the unanticipated volume of runoff were saturated 50
