Bone Lake SWA Implementation
This project proposes the implementation of 10 best management practices identified as having the lowest cost-benefit ratio as it relates to phosphorus reduction to downstream Moody and Bone Lakes with an estimated reduction to watershed phosphorus loads to Bone Lake by 90 pounds per year and to Moody Lake by 24 pounds per year. The Bone Lake watershed is at the ?top? of the larger watershed, making it an ideal location to begin work that will have direct improvements downstream. The 2010 6- Lakes Total Maximum Daily Load report indicates that improvements in the water quality of Moody Lake and Bone Lake will contribute to improved water quality in School Lake, Little Comfort Lake, and Comfort Lake.
Bone Lake and upstream Moody Lake are the headwaters of the Comfort Lake-Forest Lake Watershed District (CLFLWD) northern flow network, and as such, their water quality sets the stage for downstream waters, particularly the impaired waters of School Lake, Little Comfort Lake, Comfort Lake, the Sunrise River, and ultimately Lake St. Croix. This project proposes the implementation of 10 best management practices (BMPs) identified as having the lowest cost-benefit ratio as it relates to phosphorus reduction to downstream Moody and Bone Lakes. These BMPs are estimated to reduce watershed phosphorus loads to Bone Lake by 90 lb/yr and to Moody Lake by 24 lb/yr, and reduce watershed sediment loads to Bone Lake by 8.2 tons/yr and to Moody Lake by 4.9 tons/yr.
The Bone Lake 10-year growing season average phosphorus concentration has been consistently trending towards the North Central Hardwood Forest ecoregion standard of 40 ?g/L since a high of 60 ?g/L at the time of the 2010 Six Lakes Total Maximum Daily Load (TMDL) report, with the most recent 10-year average of 37 ?g/L. Modest phosphorus reductions to Bone Lake are needed to maintain achievement of water quality standards and remove Bone Lake from the impaired waters list, making this a statewide priority lake. In addition, watershed and internal phosphorus load reductions needed to achieve the North Central Hardwood Forest standard of 40 ?g/L in Moody Lake will be completed through other projects in 2019, and implementation of additional watershed BMPs will protect the water quality improvements in Moody Lake and prevent future degradation of the landscape.
The Bone Lake watershed is at the ?top? of the larger watershed, making it an ideal location to begin work that will have direct improvements downstream. The 2010 6- Lakes TMDL report indicates that improvements in the water quality of Moody Lake and Bone Lake will contribute to improved water quality in School Lake, Little Comfort Lake, and Comfort Lake.

(b) $6,882,000 the first year and $12,618,000 the second year are for grants to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
Implementation of the 10 projects will reduce watershed phosphorus loads to Bone Lake by 90 lb/yr and to Moody Lake by 24 lb/yr, and reduce watershed sediment loads to Bone Lake by 8.2 tons/yr and to Moody Lake by 4.9 tons/yr.
Grant funds used for the development of agricultural conservation program, and implementation of 20 acres of agricultural practices reducing phosphorus by 14.4 lb/yr at edge of field; and 9.2 pounds at Bone Lake itself. An additional 47 acres of conservation practices were implemented as a result of project development activities, though not directly funded through the grant (34.2 lb/yr phosphorus reduction). This grant was 34% spent.
