Pond Boss Forums GENERAL QUESTIONS Muddy water Feeder Creek Sediment Control

I did some more work on this issue lately...I added some more rock to the low head weir between my pond and the upper pond - this thing works like a champ in low flow and my shallow water areas are much clearer due to the sediment filtering/trapping going on in this location. I still need to widen the weir a bit more to capture even more sediment.

The creek weir is a constant pain. The creek eroded the bank adjacent to the weir a bit so I've reinforced with some sapling poles hammered into the creek bed along the bank. I added a small weir of poles supporting a stack of 6" and smaller logs in a narrow creek run about 20 yard upstream of the cinder block weir.

I decided to gauge the potential for flow and source of all the sedimentation over the last decade. Several HUGE trees have fallen upstream in the 4 branches of the feeder creek, the trees rerouted the creek bed and its carving a new path through the ravines. One branch has a very large natural rock weir/water fall but the other 3 are extremely deep ravines with nothing to stop or slowdown the inflow of runoff.

I have come to the conclusion that a few small but well built weirs will still help contain sediment (I shoved quite a bit already this spring) before it enters the pond. It also cuts down on bank erosion and further sediment load. I addition, the sediment build up at the mouth of the creek has started to seed and grow a very nice stand of mixed grasses!

All in all this project seems to be improving water quality in my pond and plant diversity. I'll update with more pictures and results when available. I have gotten permission to use an old access road to load material down the pond and will be able to add more rock, bricks, blocks and aggregate as needed.
