The pond that borders holes 7, 8, and 12 serves as the course irrigation source. Water is drawn from the deep water channel and stored in the pond until it is pumped out to irrigate the course. The water level is frequently raised and lowered during these cycles and has resulted in some undermining of the concrete rim. Unfortunately, there is no liner or erosion control installed along the bank of the pond. I'm sure some money was saved during this project, but it looks like future repairs will return any of those savings.
This small portion in the photos was washed out all the way to the rough on #12 resulting in its collapse. Much of the rim is close to this same situation and contractors and engineers have been contacted to submit bids for the repair. Until then, we will repair any eroded sections one at a time. We removed the sunken soil, back filled with 12 inches or more of crushed rock, topped that with a synthetic liner, and finally, filled in the rest with soil. This process should produce a miniature rip-rap effect. The rock will protect the soil from the undulation of the water level and keep it from washing away. Since there are no waves hitting the side, the small rock should be efficient. However, this small repair does not support the cement ring, it only protects the surrounding soil. We will continue to monitor the situation and keep you updated on the progress.
