The screen would just clog with small twigs and leaves (and muck). Pumps- Started with a rented trash pump that was very efficient in moving water but not the accumulated muck. Mechanical removal- with the limited entry width the excavator could only use a machine with a limited reach that couldn't get to the worst of the pond (the middle). (In other words I've only got 2 feet of water on top of many more feet of muck). When I put a canoe in the pond and push a stick in, the muck starts around 24" down and the stick can easily push another 2 to 3 feet into muck. The pond was made 40 years ago when someone dammed the stream. I have a small stream fed pond (20'x40') in Northern Michigan that is surrounded by mature trees.
