I had a 5-acre lake built last year it is about half way full it probably wont be filled till next summer. In the mean time I want to protect my emergency spillway from erosion just in case the drop inlet does not handle all the water. It is aprox. 30 wide would it be a good idea to have several truck loads of large rock poured and spread out or have concrete poured? Any input would be great.
