Greetings, Lake Vilbig Residents!

This letter is to discuss our October 2022 management efforts. I came out once in October on the 27th. Now it's Fall. October has been interesting. I believe that October is generally our second or third wettest month. And we finally got some much-needed rain.


Cooler temperatures have affected the lake. Water temps have cooled off considerably in a month. We have had relatively mild overnight temperatures. Sure, a few nights got into the thirties, but we have been in the 50s and 60s. But this changes the lake temps considerably. I registered temperatures around 70F, a few degrees warmer or cooler in spots. That is 10 degrees cooler in only a month. We can anticipate this trend to continue as winter approaches. But cooler temps are a good thing. I didn't see any specific examples, but I would not be surprised if we don't have some bluegill spawning right now.


While we have had some rain, it has helped maintain water levels. The ground is so dry that it soaks up much of the rain before it can create a lot of runoff. But that's okay, and we need it. I still like watercolor, especially for newly hatched fish and all shad species.


pH was still high. 8.5.Alkalinity was stable at 130 ppm.


Vegetation still is at a minimum. That is a great thing. We are starting to see some bird activity. It won't be long before the lake is covered in all those birds we see every winter. Cormorants are beginning to move back in. It is only a matter of time.


Overall we are looking good heading into late fall winter. Things will eventually stabilize. As winter approaches, we are still in that transitional period between Fall and winter called Fall.


Thanks, Vilbig Residents!
