My pond sounds alot like yours. We had a creek and gully where I wanted the pond. I do not like creek water running into my pond because of silt, and other unwanted stuff. I spent $4500.oo running a 24" pipe around the pond site. At the beginning of the pond I built a large concrete headwall to divert the creek water around the pond during high water and open a valve to an 8" pipe that I can open into the pond if I want to add water. My pond is about 1 1/2 acres and I love the part of keeping the silty water out of my pond but being able to add water during a trickle flow. I would think twice about heavy rains flowing into my pond uncontrolled.
