a Bagley Urban Runoff Project-Red Lake WD ~_ _ The Red Lake Watershed. District, in working with several partners for the Clearwater River Nonpoint Study Partnership Project, identified the Clearwater River as being in need ofwater quality improvement. The District administered an in-depth analysis ofthe `;~"~ water quality in the river and the effects of land use on the water. An offshoot of that program conducted by a partner in the project identified the City of Bagley as a site `< where runoffcontrols could have a significant impact on Clearwater River quality. ~~'" ' ' In 1995, they studied the subwatersheds in the City and proposed several control measures _ including the construction of several sediment control ponds. Unfortunately, many ~ attempts at initiating the project by the SWCD were unsuccessful due to the lack of - ~ ~;:` ~ funding and administrative muscle. `°~`~~ ~~.;~~ ~ ~~- '~ .~' The Red Lake Watershed District took an interest in the sediment pond project and took '~"`~` ~ ~~~~~ ~, ;,.°`_ ~~,~- it on as official RLWD Project #151 in 2001. With their substantial staff and financial assistance, engineers were hired to develop, plan, and design three ponds that would intercept nearly 70% of the nwofffrom the City. The expertise of the watershed and their experience in developing and carrying out major constructing projects dealing with water resources proved invaluable in evaluating the potential project, developing suitable designs, acquiring the land, developing contract documents, securing bids, selecting a contractor, and managing the project and its completion. Originally estimated at a construction cost of over $200,000, the construction costs came in well under budget and with all major components in place on time. This was a wonderful collaborative project with many partners ranging from the Minnesota Department of Transportation to the Bagley Elementary BELL project students. Trout Habitat Preservation Project -Brown's Creek WD The Trout Habitat Preservation Project included an analysis of historic natural overland drainage routes and the design/implementation of a combined wetland creation-infiltration groundwater recharge system. The results of this project set the stage for environmentally sound stormwater management in other basins of the Brown's Creek watershed as well as other trout stream watersheds in Minnesota. Standard engineering approaches to provide outlet control on Goggins Lake (e.g., placement of an outlet pipe) were not a practical solution due to the potential impacts of stormwater discharge to Brown's Creek, a DNR designated trout stream. Since thermal impacts to the trout fisheries of Brown's Creek was one of the primary concerns, the solution emphasized infiltration management to recharge groundwater and reduce surface water runoff, while reducing the flooding problems on Goggins Lake. The Trout Habitat Preservation Project alleviates flooding and protects the trout fisheries of Brown's Creek by: 1. Lowerinn the elevation of Goggins and School Section Lake to an acceptable level where significant flood damage reduction is accomplished. 2. Protective and enhancing the trout fisheries of Brown's Creek by minimizing thermal impacts and promoting groundwater recharge. 3. Incorporating a time and temperature dependent valve on the Goggins Lake outlet. 4. Incorporating soft engineering that mimics the natural hydrology of the area into the design. 5. Protectinn other natural resources of the Brown's Creek watershed such as threatened and endangered plants and animals and rare plant communities that could be negatively impacted by standard stonnwater management practices. 6. Providing design standards and protocols to outlet stormwater from other land- lockedbasins in the Brown's Creek watershed.
