I raised the level of this pond recently. This one actually went as planned. Inserted a 6" plastic schedule 40 pipe extender, cut a 6" 90 degree fitting to the height I wanted the water, and installed it on the pipe extender. It all fit tight enough I did not even glue it. Just put a single self tapping screw in the top of the 90 to make sure it stayed in place.
Raised the water level about 6". Should give some added insurance against winter kill for the RES I raise in this pond. There is hardly any dam height above water level (maybe 6-8") but the emergency spillway is about 3" above the new full pool level and this pond gets very limited runoff (maybe 2 acres). It does not get near the inflow as its sister sediment pond and the dam has very good grass established.
