pondsea:

You can get some ideas from the disucssion Brettski started here.

Here is what I have at my first pond. If the screen gets clogged at the waterline, overflow water runs below that clog to reach the drain. If it REALLY gets clogged up, it will run around the backside at a higher water level (before the emergency spillway level is reached).

Since there is a heavy grid on the drain box above, screening is not really needed to stop potentially clogging trash.

Currently on my new pond, I have 5 T-posts driven into the bottom in front of the drain inlet in a semi-circle with 3 short T-posts tied horizontally across them at and above the normal water level. This has been stopping trash from entering the drain pipe okay this Spring. Later I may replace or supplement the horizontal T-posts with screening like that in the picture above.
