I had a new run off pond constructed in September 2003 and it is about .75 of an acre. It drains about 12 acres. The deepest part is about 12-13 feet. My pond is located in northeast Iowa and when it was constructed we were in the middle of about a four month drought. Before the frost came out of the ground we got about an inch of rain on top of a foot of snow that just about filled my pond. When the frost went out, so did my pond relatively quickly. We have had four inches of rain in the last 3-4 weeks and my pond is about a quarter to a third full. I am sure the ground has absorbed a lot of moisture. Will it take awhile for the soil to saturate and my pond to gain in depth or does it sound like I am losing water? I haven't noticed any leaks and I had the botton lined very well with blue clay. Any suggestions? Should I just be patient?
