I have a big problem. I drained my 105 acre lake and killed all the fish and restocked in 2006. The lake is old - 90 years with lots of silt and clay. It is constantly muddy and clears up in the fall once the rains come and flood the shallow areas that have grass growing. Problem is the fish are white and look unhealthy and only really get 2-3 months of good fishing in until spring winds kick up and stir up again and suspend clay particles. Now that the lake is low, should I consider lining the entire shallow (10 acres) with crushed limestone or gypsum rock to help settle year round? I need to act quickly as I have time with this heat and drought to get equipment in the lake bed.
