Increase the numbers of large brown trout (>12 inches) by improving stream habitat. Reduce stream sediment load from reduced bank erosion and improved stream channel geomorphology.
MNDNR Lanesboro Habitat Improvement Crew is doing the construction on this Win-Cres TU funded project. Volunteers from this chapter have provided great assistance with tree and brush removal. This project was completed Fall 2014. Since completion, trout biomass has increased from ~160 lbs/acre (2014) to ~240 lbs/acre (2015) and ~235 lbs/acre (2016). Estimates of Brown Trout >12 inches has been at a mean of 122/mile since the project and was at a mean of 78/mile for the decade before the project.
This project included -
- Rip-rapping of stream banks
- Sloping of stream banks
- Installation of structures for overhead cover
- Installation of erosion control blankets
- Mulching and seeding with native vegetation
