Forum explores unique challenges and benefits of shallow lakes

Event planned for April 25 at the Minnesota Landscape Arboretum

Not all lakes are created equal and that certainly is the case with the more than 11,000 lakes in Minnesota, and while every lake is different, there is a particular distinction between deep lakes and shallow lakes. Shallow lakes pose different challenges and benefits and need to be managed differently than their deep counterparts.


The 2015 Shallow Lakes Forum will focus on techniques for managing shallow lakes, and the role of plants in this management. The event will be held on Saturday, April 25 from 8:30 a.m. to 12:30 a.m. in the MacMillan Auditorium at the Minnesota Landscape Arboretum in Chanhassen.  Anyone who lives on or near a shallow lake or would like to learn more about how to properly care for shallow lakes is welcome to attend.


Shallow lakes – lakes that average 15 feet or less in depth – provide a variety of benefits, including fishing, recreation, and habitat for wildlife. Unlike a deep water lake, shallow lakes also bring some unique challenges, especially when trying to find a balance between maintaining a healthy plant community while at the same time enjoying the recreational benefits a lake provides. Shallow lakes account for about one-third of Minnesota lakes.


The forum will focus on managing shallow lakes both in the water and on land, with an emphasis on plants and the role they play in maintaining a healthy lake ecosystem. Learn from the experts about how and why shallow lakes are especially sensitive to upstream pollution, which aquatic and terrestrial plants are beneficial for providing clean water, and what you can do to help manage plants to make your shallow lake healthy and usable.


The forum will include speakers from the Freshwater Society, Wenck & Associates, Barr Engineering, Freshwater Scientific Services and Urban Ecosystems.


The fee for the forum is $15 for Arboretum members and $20 for non-members and includes a light breakfast.  To register, visit www.arboretum.umn.edu/ShallowLakes2015.aspx.



Riley-Purgatory-Bluff Creek Watershed District              
The Riley-Purgatory-Bluff Creek Watershed District  was established by order of the Minnesota Water Resources Board on July 31, 1969, pursuant to the Watershed Act [Laws 1955 c799 s1]. Originally known as the Riley-Purgatory Creek Watershed District, it became the Riley-Purgatory-Bluff Creek Watershed District in August 1984. Its function is to protect and manage the water resources within the district, which is approximately 50 square miles in surface area and encompasses the land area tributary to Riley Creek, Purgatory Creek, and Bluff Creek in Hennepin and Carver counties. Portions of the cities of Bloomington, Chanhassen, Deephaven, Eden Prairie, Minnetonka, and Shorewood are located in the district.
