Talked to a couple of the biologist working henderson area and their opinion was between the black water that had backed up during the high water and Lowered O2 from a turnover in the water column the area just went to almost 0 ppm O2.
I had thought it may have something to do w/ the spraying for the lillys and hydrilla, but when i rode across the bridge earlier this week it looks like the spraying was pretty far west and just south of I-10
