In an effort to conserve storage water in Lake McConaughy, the Central Nebraska Public Power and Irrigation District is planning to lower the water levels of other central Nebraska lakes on its supply canal system.
The irrigation district is planning to use water already in the supply canal and its associated regulating reservoirs -- including Johnson Lake, Plum Creek Lake, Jeffrey Lake and Midway Lake -- to supply irrigators through September 2.
Lake's water level will begin to recede on Aug. 12 and is expected to decline
by up to eight feet by the end of the month.
Supply Canal lakes above Johnson Lake will also decline from normal levels
during the drawdown period. Jeffrey Lake near Brady will decline by approximately four feet; Midway Lake near Cozad will drop about two feet; and Plum Creek Lake south of Lexington will be down about two feet.
Lake levels are expected to be back to normal by
mid- to late September depending upon the availability of natural flow in the
CNPPID says the
amount and timing of lake level declines may change depending upon irrigation
demands and the amount and location of any rainfall in the area.
