Award Finalist: Fish Point Park Water Quality Project recognized

Posted by PLSLWD Staff - December 19, 2016 - News, Fish Point Park Retrofits, Prior Lake

Each year, the Minnesota Association of Watershed Districts (MAWD) recognizes exceptional projects and acknowledges the outstanding work of Watershed Districts throughout the state of Minnesota with the MAWD Project of the Year Award. This year, the Prior Lake-Spring Lake Watershed District’s Fish Point Park Water Quality Project was one of three finalists for the award, announced at MAWD’s Annual Meeting in Alexandria on December 1.

The project was completed through a partnership between the Prior Lake-Spring Lake Watershed District (PLSLWD) and the City of Prior Lake and partially funded by a grant from the Board of Water and Soil Resources (BWSR)’s Clean Water Fund program.

Stormwater runoff from over 89 acres of land is funneled through Fish Point Park before it enters Lower Prior Lake, making it an ideal location for a stormwater treatment train. This project includes four elements: a wetland enhancement, a water control structure, a prairie restoration, and an iron-sand filter. Together, these four BMPs work to reduce the amount of phosphorus entering the lake by 34 pounds per year.

The last lake in the Spring and Prior chain of lakes, Lower Prior Lake is a regionally important recreational and ecological resource. Unlike the other two lakes in the chain, it remains off the Impaired Waters list and PLSLWD and the City of Prior Lake want to keep it that way. Given the urban watershed that surrounds this lake, significant actions to reduce untreated stormwater needed to be taken.

If you’d like to see the project for yourself, Fish Point Park is located west of Highway 13 at 15111 Fish Point Road in Prior Lake.

To learn more about the project visit the Fish Point Park project page on the District’s website or call the District at 952-447-4166.

Project Summary

Lower Prior Lake is widely used as a local and regional recreational amenity, particularly for boating and fishing. In July 2013, Prior Lake-Spring Lake Watershed District wrapped up a Diagnostic and Feasibility study which determined that water quality in the majority of the lake is determined by the direct drainage from the watershed, called out untreated and undertreated areas, and identified specific projects and opportunities by subwatershed.
The proposed project includes three elements:
1) retrofitting an existing ditch section with in-line iron-sand filters
2) expanding storage capacity and creating wetland upstream of the ditch with an outlet structure
3) restoring native prairie plants

Fish Point Park Map

Following a neighborhood meeting held in July 2015, several changes were made to the original plans to accommodate neighbors’ feedback. The total wetland enhancement area was reduced in size which resulted in the removal of fewer trees. The revised plans also reduced the size of the native prairie planting area in order to retain the flat playing field area and sledding hill. In addition, some of the fill from the excavation of the ponding area was placed on the playing field but most of the fill was taken off-site to preserve the playing field and sledding hill. Lastly, the size of the ponding area was increased as a result of neighbors’ desires for a larger area of open water in the wetland.

Anticipated Outcomes

The subwatershed in which this project is located was identified as undertreated in the Diagnostic and Feasibility study. By improving the efficiency of the existing treatment train from 35% to an estimated 78%, the overall load to Lower Prior Lake would be reduced by 19 lbs, to 10lbs/year. The three elements in this project will work together to enhance their collective effectiveness, making the overall project benefits greater than the sum of the benefit provided by each part.

Project Progress in 2015: Construction Underway

In 2015, the Watershed District finalized plans for the Fish Point Park Water Quality Improvement project. A neighborhood meeting was held in July 2015 to share the project plans with neighbors and receive their feedback. Plans were then revised to incorporate neighborhood feedback.

In October, a Conservation Corps Minnesota crew began tree and brush removal at the site to prepare for the excavation of the wetland pond. Contractors then removed the remaining trees to complete the site preparation work. The wetland expansion will increase the stormwater storage capacity of the site.

Crews completed the excavation of the ponding area during the first week of November. While most of the fill was removed from the site, some of the excess fill was spread on the field net to the basketball court and along the western edge of the wetland area. The installation of the outlet structures and the iron sand filter is underway and should be completed by mid-November.

Multiple best management practices are in place to prevent erosion and keep sediment on site. Street sweepers are also being used to keep the road in front of the park clean.

Construction should largely be complete by the end of 2015.

Next steps:

Construction should be largely complete by December 2015. There will be a neighborhood meeting held in April 2016 to discuss the vegetation plans for the site. The vegetation plans will then be finalized and planting will occur later that spring. There will be opportunities for volunteers to help with planting so stay tuned for more details!

Prior Lake – Spring Lake Watershed District

The District covers about 42 square miles in Scott County, MN. Water in the PLSLWD flows mainly from the southwest to the northeast through Spring, Upper Prior and Lower Prior Lakes, and then north through the Prior Lake Outlet Channel to the Minnesota River near Valley Fair amusement park.
