Normally we would have had enough rain over the winter to fill the pond. But since we only had a couple rains that produced a minimal amount of runoff, the water level is still below full pool a foot or so. But the island in the middle is just barely visible where in the pictures in the above post it raises a foot or so above water at the old pond level full pool. Will post some more pictures when it gets to full pool. Been a dry winter.

The post above has pictures of raising and extending the dam. These pictures are after I installed the 8" schedule 40 sewer pipe and filled in the area where the earthen overflow had been and extended the dam appropriately. The emergency overflow is now basically both sides of the pond, which is about 8" above full pool. In other words, when the pipe is running full, the water will start around the dam on both sides for the emergency outlet of excess water. I made the emergency so close to the overflow pipe level to get what I felt was the maximum water level available.

An update about the old refurbished pond. After several 1-2" rains it is at full pool and running out the overflow. Pictures with descriptions below.
