My pond is 2 years old now. When we let the water in it filled in about 2 1/2 months.The pond is 1 1/4 acres and 13 feet deep. A small spring that flows into a man made creek helps to fill it. This past summer was very dry here in Ohio and it dropped about 5 feet. This didn`t concern me much due to weather and every pond around was very low. Now the fall rains are here and it is filling but, I have noticed it dropped about and inch in 2 days after a light rain was around. There is water behind one side of my pond but could be runoff. What do you guys think? Time to panick?
