I built my pond in what is known here as a "seasonal creek". It runs during our rainy season, which is usually 8 - 9 months! The first pond was smaller and I didn't have any fish or plants, so just kind of let it go. During the winter it filled up with smelly silt and was not good. I have now dug the pond out bigger, got plants and fish and I want it to stay nice. I have the water level adjusted so the amount that flows in will flow out the other end. My question/hope is that if I make a bog area on the in-flowing side, along with several small dips in the "creek" bed , will that catch the silt and keep it out of the pond?
