Until 1990, the county government regularly conducted
dredging projects of the lake to remove accumulated sediment. Since that time dredging was deferred for budgetary reasons. In 2008, the County started preparations to dredge sediment from the lake during 2010-2011. The dredging project will improve water quality, as well as boating and fishing conditions.
