2014 Shoreline Survey Results
Every 4-6 years, FLARA commissions a vegetation study to monitor the condition of our lake. A study was most recently performed in the summer of 2014 by Freshwater Scientific Services; a link to the complete 2014 report can be found below.
To summarize the 2014 report findings -- the condition of Fish Lake has not changed dramatically from the study that was performed in 2009. There were a few anomalies, but those were likely due to the unusual weather conditions we had in the 2014 winter and spring. There is nothing in the report that required immediate action.
The main aquatic invasive species (AIS) we have in Fish Lake is the Eurasian milfoil (Myriophyllum spicatum). It is not a problem in the entire lake, but it is concentrated in several places. The other AIS (that is a problem in several Twin Cities lakes) is curly-leaf pondweed (Potamogeton crispus) and is present in Fish Lake, but only in a few places. The native vegetation--which is desirable in a lake to discourage AIS, provide food for our fish population, filter the water, and stabilize the lake bottom and shoreline--is present, but not as diverse as we'd like to see.
