The two pipes for this pond end in a ditch that drains about 60 acres+. I was worried that the 2" pipe would fill with mud so I added an elbow and another 2 feet of pipe to get it above the water level during a flood.

While I was installing the elbow I noticed that pipes were located in a big bend in the ditch. The ditch is shaped like a U with the pipes at the bottom. My plan is to dig a ditch to connect the top of the U and fill in the ditch just upstream of the pipes. This will stop the flow by the pipes and hopefully keep them from filling with mud.
