A 2400 pound fish story! Utilizing an electrofishing boat (very cool 😎), the Lake County Health Department worked with our volunteers this past week to remove 1.2 tons of invasive carp!! Don't feel bad for the carp - these bottom feeding fish reduce water clarity and stir up phosphorus-containing sediments, which contributes to algae blooms. Less carp = a healthier lake 🙂
A HUGE thank-you to the LCHD and our amazing volunteers 💚

A BIG thank you to everyone who came out to help yesterday with our Long Lake Cleanup❣️ Because of our efforts, we were able to remove more than three truck loads of garbage from the lake and surrounding shores! Special shout-out to Grant Township Highway Department for hauling it all away :-) The day was a lot of fun and we are so grateful to everyone who was able to participate.

We hope to see everyone in the future at the next cleanup event!

Anyone wondering why our Long Lake water level is staying so high right now? This video shows what is currently going on at the LLISA dam. Usually the dam spillway is approximately 18 inches higher than the Chain O'Lakes and the water from our lake naturally spills downstream over the dam. However this week, the water in chain is so high that our Long Lake water level is about the same level at the dam. Ah, Mother Nature. Even with the sluice gate fully open, the water is only able to flow very slowly downstream from Long Lake.
