Tanners Lake 5th Street Basin
A wetland modification to help improve the water quality of Tanners Lake.
The Tanners Lake 5th Street Basin is located just north of Tanners Lake Park, near the intersection of 5th Street and Grafton Avenue North. The management plan identified a wetland north of the lake as a prime resource for improving the quality of stormwater from the largest contributing drainage area. The basin was a partially-filled wetland in a degraded condition, prompting construction of a multi-celled treatment system for stormwater.
The basin was designed to remove approximately 60 percent of the phosphorus load before slowly releasing treated waters to Tanners Lake. The area has two ponding areas with permanent standing water and two permeable weirs to slow the flow of water through the system. Construction was completed in 1997. The area was seeded and planted with native seedling plugs in fall 1997 and spring 1998.
*This project is part of a larger plan called Tanners Water Quality Improvements, which was implemented based on results of a diagnostic feasibility study that began in 1989.
