Description:

Hard to find a spot in the wall of the lake without these. While watching them for 1-2 minutes quite a few of them were falling of the wall to the mud below. I'm not sure what was going on. The day was unusually warm so surface temps could have been high and the lake is definitely more brackish now than a few months back. I wonder how dissolved oxygen changes due to salinity in the lake, sure there is less as the water becomes warmer.
