We received six inches of rain Sunday afternoon into Monday morning so needless to say our drainage ditch was rushing into the pond. Our 3 acre body of water rose nearly a foot!
I walked the property yesterday and did not find any fish below the spillway! We've installed 2 fence posts with mesh wire across the spillway. Small fish could pass through, but I didn't find any. The mesh wire is collecting lots of TRASH for sure!
One thing I'll say that might benefit others is to ensure during pond construction your spillway is wide enough. Our construction certainly has some faults, but the spillway was done very well. It is wide with an ever so slightly downhill slope. The water is easing out instead of rushing out hopefully eliminating erosion issues.
