Project Number: ML-22
Project Status | Complete
This project was constructed in the winter of 2024-2025 and is now complete.
Project Funding | Not Grant Funded
The total cost of this project was just under $405,000 and was funded through taxes collected from all residents of the Bassett Creek Watershed area through the BCWMC Capital Improvement Program.
Project Description
This project restored a small stream that was actively eroding near Medicine Lake and which drains into Plymouth Creek and then into the West Medicine Lake Park Water Quality ponds. This project stabilized streambanks, reduced sediment and nutrient pollution reaching Medicine Lake, improved in-stream and riparian habitats, removed over two acres of buckthorn, and prevented future channel erosion along a 1,000-foot section of the stream that drains into Plymouth Creek just upstream of Medicine Lake. The project reduced total phosphorus and total suspended solids entering the lake by and estimated 7.3 lbs. per year and 14,690 lbs per year, respectively.
In addition to clearing buckthorn and removing dead and dying ash trees and box elder trees, some healthy desirable trees were also removed in order to access the site, grade streambanks to a stabilized slope, and protect infrastructure. Twenty new trees were planted to replace lost trees.
