I had always wanted to see what it was like when the pond was filling. I converted my rocket cam to take time lapse pictures every 5 minutes. They closed the head gate at noon on Saturday. We stayed till about 8 p.m., even getting the canoes out for bit.
When we came back Monday, we found two problems. First, the pond was drained again. There was a problem with the head gate and they had to empty it to fix it. Second, the camera apparently drained the battery and only operated during the day while the sun was hitting the charger. That is what I get for wiring it up the night before.
