Sedimentation in Lake Onalaska, Navigation Pool 7, Upper Mississippi River,
since impoundment: Water Resources Bulletin, v. 23, no. 2, p. 221-226.

Abstract: 

Sediment accumulation was evaluated in Lake Onalaska, a 2800-ha backwater
impoundment on the Upper  Mississippi River. Computer programs were used to
process fathometric charts and generate an extensive data  set on water depth for
the lake. Comparison of 1983 survey data with pre-impoundment (before 1937)
data  showed that Lake Onalaska had lost less than 10 percent of its original mean
depth in the 46 years since  impoundment. Previous estimates of sedimentation
rates based on Cesium-137 sediment core analysis appear to  have been too high.
