Two large, actively eroding gullies located a few miles apart in Amador Township are contributing tremendous loads of phosphorus and sediment to the St. Croix River. One gully (Gully A) includes a major agricultural gully, severe road erosion, and sediment deposits of a foot or more thick in a state park. The second gully (Gully B) is over 4 feet deep, adjacent to a road, and is an annual problem. Stabilizing these two gullies will greatly reduce the sediment and phosphorus loading to the St. Croix River, which will help meet the reduction goal of the Lake St.
Using a previous escarpment gully project as a model, the Chisago Soil and Water Conservation District will complete a similar inventory of actively eroding gullies along the Lower Sunrise River from the Kost Dam south to the confluence with the St. Croix, which includes the North Branch of the Sunrise, Hay Creek, and the Sunrise River main branch. There are major erosion issues along this stretch of river, no organized and efficient way to begin work in the area. The inventory report will provide the missing link.
The Chisago Soil and Water Conservation District has been successful in implementing Best Management Practices in certain targeted locations within the county, including the prioritized and assessed areas of Chisago City, Lindstrom, and Center City. However, there are many areas that want to implement conservation projects but aren't within targeted areas. This award will empower community partners, especially lake associations, to award grants for rain gardens, shoreline buffers, and other worthwhile projects to improve water quality.
Goose, East and West Rush Lakes are not meeting state water quality standards due to excessive phosphorus. These are three of the worst lakes in Chisago County in terms of water quality, yet also some of the most heavily used lakes for recreation. The quality of the water in the St. Croix River is directly influenced by the poor quality water leaving East Rush, West Rush, and Goose Lakes.
Bone Lake and upstream Moody Lake are the headwaters of the Comfort Lake-Forest Lake Watershed District northern flow network, and as such, their water quality sets the stage for downstream waters, particularly Comfort Lake, the Sunrise River, and ultimately Lake St. Croix. This project proposes the implementation of six wetland restorations located along the tributary identified as the single highest source of phosphorus loading to Bone Lake. These wetland restorations are estimated to reduce watershed phosphorus loads to Bone Lake by 50 pounds per year.
This feasibility study will produce strategies for wetland restoration and ditch hydrology changes to reduce the amount of phosphorus and solids that drain into Typo and Martin Lakes, the Sunrise River and St. Croix River. Total Maximum Daily Loads and other plans have identified this area as key for pollutant reduction, and the study will determine scope and effects of potential projects, allowing the district to prioritize those that will have the great impact on water quality.
This project will identify and prioritize opportunities to implement a multipurpose drainage management plan that will provide adequate drainage capacity, reduce peak flows and flooding and reduce erosion and sediment loading, improving water quality to the West Branch Rum River.
The goal of this project is to adapt and expand the existing successful Master Water Stewards program to engage citizens and catalyze clean water projects in suburban, exurban and rural communities of Washington and southern Chisago Counties. As part of this project, 20 citizens' stewards will be recruited and trained to work in partnership with the Washington Conservation District and area watershed management organizations to implement clean water projects in identified priority areas.
This project will develop an enhanced street sweeping plan for the City of Forest Lake that optimizes phosphorus removal from increasing sweeping frequency with the cost of additional sweeps. In addition, this project will identify road-specific street sweeping timing and frequency, quantify expected phosphorus load reductions, itemize costs of enhanced street sweeping, and recommend funding options to the City of Forest Lake.
This project will install nearly 800 linear feet of restored lakeshore with an emphasis on bioengineering techniques, native plants and locating buffers/swales at points of concentrated overland flow into Green Lake. By targeting properties that are eroding and/or with concentrated overland flow to the lake we will reduce suspended solids discharge by 16,697 lbs/yr and phosphorus by 1.3 lbs/yr.
This project will result in the installation of give water quality practices totaling 350 linear feet of restored lakeshore and 6,000 square feet of native plant stormwater management. By targeting properties that are eroding and/or with concentrated overland flow to the lake, pollutant discharge to the lake will be reduced.
This grant will fund the creation of a new Coordinator position with a primary focus on the Mille Lacs Lake subwatershed. Although not currently impaired, the Lake faces increasing development and land use pressure. Implementation of protection strategies is essential to the Lake's long-term health but current staffing does not allow sufficient time to be spent on project development and outreach to identify interested landowners.
Golden Lake does not meet state water quality standards due to high phosphorus levels. The proposed iron enhanced sand filter basin was identified in the Golden Lake Subwatershed Stormwater Retrofit Analysis to be one of the most cost effective remaining practices for reducing external phosphorus loads to Golden Lake. This project, paired with two previously installed upstream Best Management Practices, will achieve on average, 84% of the phosphorus reduction goal for the watershed.
The Project and Outreach Coordinator will facilitate efforts within the watershed to provide landowner support and assistance in identifying areas in need of conservation plans and best management practices. The coordinator would use the Watershed Protection and Restoration Strategy Report and county water plans to target and prioritize outreach and education to maximize water quality benefits. This will greatly multiply the number of educated landowners in the watershed and increase the number of projects implemented.
The Mississippi River is currently listed as impaired for turbidity. Eroding riverbanks are one of the causes of this impairment. An inventory was completed in 2016 of riverbank condition along 5.8-miles of the Mississippi River that is within the City of Ramsey. In this inventory, ten severe to very severe eroding stretches spanning 27 private properties and 6,550 linear feet were identified. Cumulatively, these sites contribute 5,148 tons of sediment per year to the river.
This project targets one of Chisago County's few remaining large dairy operations. It is situated on the top of the St. Croix River escarpment and drains over the bluff to the St. Croix River. This project includes installation of several practices in the feedlot area, including critical area planting to help stabilize a gully formed through the feedlot. There are also two other gullies located at the edge of fields or pasture areas that will be stabilized using water and sediment control structures, grade stabilization practices, or diversions.
