Our fundraising goal is $25,000, to allow us to fund various water quality improvement strategies, including AIS training, carp population management strategies, and community education.
One of the key drivers of the poor water quality in the Long Lake Creek Watershed is the overabundance of invasive carp.
These large, aggressive, non-native fish drive out native species like walleye and bluegill, and destroy the habitat for beneficial aquatic plants. They stir up phosphorous that decreases water clarity and promotes algae growth. They move throughout the entire seven lakes and many streams of the Long Lake Creek Watershed (fun fact: carp can move in < 2 inches of water!) and damage the ecosystem wherever they go.
After successfully radio-tagging carp in the watershed over the past several years, to gather population estimates, we (in conjunction with MCWD) identified areas of ingress and egress, and determined smart locations for a box netting effort. Working with outside vendors, LLWA funded several removal projects. We were able to corn bait shoreline locations (with 100 pounds of corn a night!) to attract carp, essentially "training" them to go to designated locations for the food. After a week of "training," we are able to extract over 1000 carp.
The carp were over 22 inches in length and averaged almost 10 pounds. The good news is that migration of carp into Long Lake is limited and if we can continue to contain the carp population, we will reach the goal of less than 100 pounds pre acre, which is the management goal for carp to have only minimal impacts on lake ecosystems.
Thanks to the local lakeshore residents who allowed us access to their docks and lakeshore during this process!

You can help!
Any size donation makes a difference – Please consider supporting Long Lake Waters Association in our quest to improve water quality!
We also host educational seminars to help residents understand the drivers of water quality, and create community around our watershed health. We conduct AIS training to help residents identify, track and report invasive species, and support local efforts to keep our waters clean. We welcome neighborhood input and support.
We are on a mission to protect and enhance the water quality within the Long Lake Watershed!

The Long Lake Creek Watershed covers over 7,619 acres, and includes seven lakes (School, Holy Name, Mooney, Wolsfeld, Dickey's, Long Lake and Tanager on Lake Minnetonka), as well as all the surrounding streams and wetlands. It encompasses three cities (Medina, Orono and Long Lake) and over 6,000 households.
Long Lake Creek Watershed is also the headwater for Lake Minnetonka and Minnehaha Creek, which in turn flows into the Mississippi River.
Many Minnesota residents and visitors enjoy these lakes, streams and wetlands for fishing, boating, birding, swimming and hiking, but many don’t know that the Long Lake Creek watershed is seriously degraded, and its problems are impacting the downstream water bodies.
