Nearshore Fisheries Survey

GLEA worked with retired DNR staff on conducting a Nearshore Fisheries Survey for the lake. This survey has been done 4 times on Geneva Lake, beginning in 1978 and the most recent one conducted in 2018.  The report not only describes current fish populations, but also compares them to previous surveys as well. 

A total of 18 sites were sampled to understand the nearshore fish population. Gar, darter species, bass, panfish (bluegill, sunfish, perch, rock bass), bullheads, and killifish, where among just some of the species found.  Read the full report below!

Aquatic Plant PI Survey

GLEA worked with Southeastern Wisconsin Regional Planning Commission on our Annual Aquatic Plant PI Survey.


Through sampling a grid of points on the lake, we can document the overall plant diversity as well as locations of certain species. This survey also helps us monitor where starry stonewort is and how it spreads year to year. Look out for that report later this year!

Boat Count

GLEA conducted the annual boat count early August to assess boats docked and moored on Geneva Lake. Motorized boats, sailboats, personal watercraft, and non-motorized vessels, are all included. The GLEA spends a day on the water counting boats on the shore and collecting numbers from storage facilities and marinas. The "Data" tab has more information on comparative counts for past years.
