 The  Aquatic Invasive Starry Stonewort

 Starry  stonewort 's reproductive bulbil.

The Geneva Lake Environmental Agency would like to thank all the Geneva Lake lovers that contributed to our starry stonewort management.  Although things are now a bit different than a year ago, managing invasive plants is still a priority for the Geneva Lake Environmental Agency. Money raised through Go-Fund Me will be used for starry stonewort and aquatic invasive species control.  

At present the GLEA is planning on conducting another lake-wide aquatic plant survey during the summer of 2020 to see if the plant has spread to other areas in the lake.  Education of boaters to clean their boats, trailer, bilges, bait buckets and live wells as they move from one lake to another is vital in controlling the spread of starry stonewort to other lakes.  Just as important in controlling the spread of starry stonewort within Geneva Lake is the cleaning of anchors, of plant material and sediment (mud) as you move from site to site on Geneva Lake. 


It is illegal to leave a launch site with vegetation hanging on your vehicle, boat or trailer.  You will not be allowed to launch on Geneva Lake if you do not follow the required boat cleaning before you launch. See the Wisconsin Department of Natural Resources web site (

for information on boat transportation and bait laws.

About The Geneva Lake Environmental Agency

The Geneva Lake Environmental Agency was formed in the early 1970's by a group of citizens concerned about Geneva Lake's future. The Agency was formed as a shared unit of the local governments of the Towns of Linn and Walworth, the Villages of Fontana and Williams Bay and the City of Lake Geneva.

Since 1975, the Agency has operated under a Uniform Resolution and By Laws signed by the sponsoring units of government. The resolution calls for the Agency to study the 5,262 acre Geneva Lake and its 13,045 acre watershed regarding its physical, chemical and biological characteristics, water quality, lake and land use; protective measures, recreation and resource related problems and to make recommendations to protect resources, improve living conditions and foster legislation to accomplish these recommendations. This program is implemented by one full time staff member and a college intern.

All too often, many of us take the quality of the lake and diversity of plant and animal life for granted. We seem to expect a healthy and diverse lake, clean and plentiful water to view, swim, fish, and boat in. A healthy Geneva Lake also increases tourism and property values, and is good for the local economy.

Not only is it critical to protect the lake today, but it is important to protect it so we can pass it down to future generations. If we do not take steps to ensure that the Geneva Lake's water quality remains suitable for these purposes, the excellent water quality we take for granted may vanish. The Agency is determined to maintain Geneva Lake's resources by protecting, preserving, and enhancing desirable lake and watershed quality.

The most important thing one can do is to 


  • Learn about how your daily routines affect Geneva Lake by obtaining a copy of the Geneva Lake Book. Realize that we are part of the problem and an integral part of the solution.

  • Encourage your family, neighbors, community, civic groups, and governments to protect water quality.

  • Contact the Agency or other water quality advocates who have the technical ability to help us help ourselves.

  • Do not take water quality for granted. Realize that water quality is strongly related to your enjoyment of the lake, property values and an important legacy to leave for future generations.
