Temperature inversion.

Today I got a report of some dead fish in the lake on 7/9....that's never good. I checked the chemical logs and nothing has been sprayed in months that would cause an issue. Then I remember that on Wednesday we repaired a main connection drainage pipe that dumps into the lake. This might not seems significant but trust me it was.

The end of the pipe in the picture was actually floating out of the water due to the hollow ribbing that gives the pipe structural strength. To fix it Kenny just added some weights to the end of the pipe and it sank back into the water. THEN, the water that was being held back started roaring out of the end of the pipe. All of this water was coming from the lake on 5. The rapid introduction of all the new water into a system that had stabilized after the rains seems to have caused a temperature inversion in water column which is believed be the cause of the dead fish. It is not due to a chemical or fertilizer application.
