Influence of Lake Restoration Measures on Water Quality and Water Quantity in Blue Lake, Iowa. Oxbow Lake Study. Phase 3

摘要

Blue Lake, 48 km (30 mi) south of Sioux City, Iowa is one of four oxbow lakes on the floodplain of the Missouri River which provide important recreational resources to the people of western Iowa and eastern Nebraska. The other lakes are Brown's Lake, DeSoto Bend, and Lake Manawa. It was recognized in the mid-1970s that all of these lakes have problems associated with poor water quality and/or limited water quantity. Diagnostic studies were conducted on the four lakes and recommendations presented for possible restoration or improved management. Blue Lake was the first of the group to have the management recommendations implemented. The report describes the effect of the restoration measures based upon observations covering one year after the measures were put into effect.
