Project Background

 

Mitchell Lake is surrounded by residential communities and parkland.  The lake is accessible through a public lake access and extensively fished year-round by residents and other citizens.  Mitchell Lake is an important water body with nearly five miles of shoreline.  Infestations of Eurasian water milfoil and curly leaf pondweed contribute to impairment of water quality and recreational use.  Serious algal blooms occur throughout the summer, particularly in later months.

 

The Mitchell Lake Use Attainability Analysis recommended a multi-year approach to alum treatments to manage phosphorus and reduce algal blooms, and herbicide and other treatments to control invasive aquatic plants.  Implementation is expected to extend over the next decade with monitoring and reporting of success.

 

 

Current Project Status

 

District weed harvesting is proposed for 2012.

 

Water quality improvement approaches have been considered.  Destratification aeration and micro-floc are recommended
