I have a farm pond that is clogged?
Here's what I know; I have water flow through the drain pipe down to the creek. But has not changed flow rate since I began pumping the pond a week ago,. I have pumped approximately 3ft down, measuring distance on the bank/berm water level.
I have the water level down past the spill way pipe.- vertical pipe. The pipe has a seperate hole on the side from deterioration or impact from some time ago.
I put food coloring in the pipe from the pond side to see if it would pull purple die to the outlet pipe at stream. That did not happen. No water movement in pipe.
Earlier today, I stuck the 2" discharge pipe from the water pump inside the spill way pipe. Bottom of pipe is about 10'. I sprayed water into pipe to see if I could dislodge anything stuck. Keep in mind, I can not drain the water out of pipe. What you see in the picture is where the water level stays at.
I have the main valve at the base of the berm completely open. We assume the valve is operating correctly and is not seized shut. Pond drainage worked fine last year.
The outlet pipe run is about 500' to the creek. Downhill. In one picture, I highlighted the pond berm with red. So you can see the distance.
I have a camera down the spillway pipe now, but its not the easiest to get a good picture of the horizontal pipe going to valve to see if its clogged.
