Maintenance

The early activities of the Carnelian Marine Watershed District involved solving the flooding issues in the Big Marine Lake sub-watershed which included Big Carnelian Lake, Little Carnelian Lake and a series of wetland systems connecting them. A period of high precipitation in the late 70’s and early 80’s increased water levels in this land-locked basin to unacceptable levels, which flooded lake-side houses and saturated private septic systems. The flooding problems in this drainage area were alleviated by the installation of a three-mile gravity pipe which outlets this large, landlocked sub-watershed.

The District's Maintenance Program now ensures that water channels and stormwater outlet pipes remain open, water obstructions are removed and projects to improve water quality and reduce flooding—such as rain gardens— are installed, inspected and maintained.
