This is my pond, water level is a little low at the moment. I lose some out of the stream but that will change when I get my smaller pump going. Like I said, it is in progress, we don't have a lot of time to spend on it so it takes a while for us to get it complete. This was a large project for us, but we like it. I'm not sure if you can tell, but the water level even though it is low, is still over 3 1/2 feet deep, it is about 4 feet deep when full. I can see all the yuck on the bottom that I need to get in there and clean. Before the bog filter I could not keep clear water. Anyway, just my two cents.
