33 Lake Cle Elum DaOm - is an earthfill dam 165 feet high and, including the dam, a main dike, and 3 smaller saddle dikes sited along the crest of a terminal moraine, contains 1,411,000 cubic yards of material. The Bureau of Reclamation (BOR) operates the dam to provide water storage and flood control on the Cle Elum River. BOR releases water from the dam in the fall to provide lake capacity for winter and spring snowmelt and when the lake fills to storage capacity. Water released into the river increases volume and velocity that can overturn floats, rafts, canoes, and kayaks when unexpected. KRD High Line Canal flume – Kittitas Reclamation District (KRD) installed a flume on the High Line Canal that drains into the Yakima River across from Bristol Flats. KRD also developed the boat launch facility across from the flume in Bristol Flats for flume maintenance purposes. The flume discharges water from the canal into the river for 1-2 days in mid-April when KRD is charging the system and after Labor Day when water is discharged constantly to aid in flip- flop – the process of modifying irrigation operations to allow the upper Yakima River levels to drop to a more natural value during spawning season so that the fish eggs remain covered with water through the winter. KRD may also discharge water into the flume during the summer if there are any operating problems that arise that create a need to bypass the canal – an event that happens very rarely. Water discharged into the river by the flume creates a surge or wave that can upend any watercraft in the vicinity of the flume including recreational floaters, rafters, canoes, and kayaks. KRD monitors activity on the river to make sure there will be no impacts on recreational users before discharging any water into the flume. Ellensburg Water Company Diversion Dam and Fish Ladder – is operated by the privately owned Ellensburg Water Company that began operation in 1885 and currently supplies water from the Yakima River to fill 24 miles of canals with 225 lateral ditches. The dam diverts water from the Yakima River into the canal, known as the Town Ditch, that flows through Ellensburg to the southeast before terminating at the Wippel Wasteway (known as the Government Ditch) about 1 mile east of the confluence of Wilson and Cherry Creeks. Reecer, Cooke and Parke Creeks augment water flow in the Town Ditch as well as return flow from the Cascade Irrigation District and the Kittitas Reclamation District (KRD) systems. Today, the Town Ditch is the largest single water diverter in Washington State, irrigating more than 10,000 acres, half of which produces timothy hay, and providing water for lawns in Ellensburg. When properly treated to meet Department of Ecology (DOE) standards, Ditch water will eventually help recharge the aquifer that provides Ellensburg’s potable water. The Bureau of Reclamation (BOR) operates an automated hydronet station near the diversion dam that automatically transmits flow data every 15 minutes by satellite to BOR offices to determine
