IOWA CITY, Iowa – The U.S. Army Corps of Engineers, Rock Island District, will maintain the non-growing season maximum release of 10,000 cubic feet per second (cfs) at Coralville Lake due to predicted higher than normal inflows into the reservoir. Typically, reductions in outflow are made to reduce flood crests downstream of the reservoir. By maintaining 10,000 cfs at the reservoir, flood storage will be conserved for future snowmelt and runoff from rainfall this spring.
A heavy snow pack persists across much of the northern reaches of the Iowa River basin. With the higher than normal predicted inflow due to recent rainfall and snowmelt, the Coralville Lake reservoir is forecast to utilize a significant amount of flood storage early in the spring, leaving limited flood storage available for future snowmelt and rainfall later in the spring.
