Need

The Gleason Lake Management Plan identified a number of improvements to be undertaken in the subwatershed that together could significantly reduce phosphorus loading to Gleason Lake. Of particular emphasis was dredging existing stormwater ponds to regain and/or increase pollutant removal efficiency. Specific ponds identified as priorities for improvement include those described in the plan as Pond 2 (west of Dunkirk La, between 24th and 25th Avenues N), Pond 3 (of 25th Avenue N, between Fountain and Garland Avenues N), and Pond 6 (west of Dunkirk La, north of 19th Avenue N); improving Pond 8 (west of Vicksburg, La southwest of 9th and 8th Avenues N) and the Cimarron Ponds (west of Vicksburg La, between 10th and 12th Avenues N); and repairing the eroded Ditch #15 reach E3 (west Of Dunkirk La, between 22nd and 24th Avenues N).

As detailed in the Gleason Lake Management Plan, these projects are proposed as joint projects with the City of Plymouth. The specific share of construction cost as well as ongoing maintenance costs associated with these improvements would be determined by cooperative agreement prior to implementation of this project.

OutcomeTogether these improvements are estimated to remove 77 pounds of phosphorus annually, along with other pollutants such as sediment.
Estimated CostInvestigation, permitting, implementation, and project management. Funding source is the District capital levy and the City of Plymouth. The specific share of construction costs as well as ongoing maintenance costs associated with these improvements would be determined by cooperative agreement prior to implementation of this project.$566,500
