Sand Lake is a 318 acre drainage lake in northwestern Barron County. There are several perennial and intermittent streams/drainage gullies that contribute water, sediment, and nutrients to the lake. In 2016, one of the largest gullies, known locally as the NW Wash was repaired with funds provided by a WDNR lake protection grant. The NW Wash was a relatively short, but very steep and ragged gully that became a huge negative impact after a 2010 rain event that dumped more than 8” of rain over a very short period of time. The resulting runoff and gully erosion filled in a 0.12-acre area of the lake that was previously more than two feet deep in a single day (Figure 1).

Sand Lake Management District is sponsoring a Lake Protection grant to repair gulley erosion, provide agricultural BMP incentives, and monitor tributaries to document nutrient reductions. The specific project tasks include: 1) NW Gulley Washout repair; 2) Agriculture BMP incentive payments; 3) Tributary and outlet water quality monitoring; 4) Field and lake BMP educational tours. Maintenance, operation, and protection will be specified in a ten-year contract for each BMP site. The Department may perform site inspection and/or monitoring.
