Project Details

Bass, Schmidt and Pomerleau Lakes are part of a three-lake chain in the City of Plymouth, all of which were listed in 2002 as Impaired Waters for excess nutrients. Substantial watershed nutrient load reductions have been completed, and Schmidt Lake has been delisted from the 303(d) list. Internal phosphorus load from the sediments continues to be a significant issue in Bass and Pomerleau, and alum treatments are proposed to reduce 90-95% of internal phosphorus loading. After treatment both lakes are expected to be at or close to the water quality standard.

Appropriation Language

$6,882,000 the first year and $12,618,000 the second year are for grants to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.

Proposed Measurable Outcome(s)

A 90-95% decrease in internal phosphorus load, or about 455 pounds per year on Bass and 135 pounds on Pomerleau. In Bass Lake, a 0.45 m increase in clarity from 0.98 m to 1.43 m, and a reduction in summer average TP concentration from 80 g/L TP to 65 g/L. In Pomerleau Lake, a decrease in chlorophyll-a (chl-a) from 34 g/L to 29 g/L, and a reduction in average TP concentration from 103 g/L TP to 70 g/L.
