DES MOINES, Iowa (AP) — Downstream residents can breathe a little easier, now that the water level is dropping in the reservoir that protects Des Moines from Des Moines River flooding. Dayne Magneson is assistant operations project manager for Saylorville Lake, and he said Tuesday that the U.S. Army Corps of Engineers lake crested overnight less than 4 feet below full, reaching around 89.5 percent of capacity. He says the level was the sixth highest in the lake’s 41-year history. He says the figures are allowing officials to let loose “a minor sigh of relief.” Magneson also says the water will drop slowly on its way to the normal level of 11.5 percent of capacity.
