I forgot to mention this - hard to believe I left anything out of the first post. The original pond has an island in the middle of it. The two aeration stations are on either side of the island. The water level has dropped 12 inches in the last three weeks due to the heat and lack of rain or snow this past winter. I'm guessing that the water levels might drop another two to three feet if it keeps up this pace. I might be able to walk across the channel by the end of august without installing the planned bridge crossing the channel. We'll see what happens. Back to work on rocking in the stream and pond areas.
