Green Lake Eurasian Watermilfoil/Stormwater Study (CWP Grant)
Grant timeline February 2010 – June 2013
Grant dollars: $33,000 Match: $33,330 Total: $66,330
The purpose of this Research Investigation Project is to examine the relationship between the location of stormwater inlets and stands of Eurasian watermilfoil; the hypothesis is that stormwater inlets provide a means for nutrient and sediment loading that previously did not exist, and that the nutrients and sediment are providing an environment more hospitable for the propagation of EWM. Research of scientific literature yields valuable information on EWM, but no research on the hypothesized relationship has been located. Existing literature indicates that Carlson’s Trophic State Index (TSI), water column phosphorus (Madsen, 1998), sediment nitrogen (Anderson and Kalf, 1986), and percent composition of sand in sediment (Barko et al, 1986) have been examined as parameters associated with the success of EWM in lakes. This project will expand upon the available literature and upon an existing paradigm with EWM in a study that could have local, regional and national impacts on development with regards to stormwater. If the hypothesized relationship can be established, the location of new stormwater infrastructure and inlets would have to be reconsidered prior to construction.
