Butting up to the Chattahoochee National Forest this lake is very unique because it has a source of cold, clean water year around. There’s a rumor among the old timers on the mountain that this lake use to be full of big brown trout. Our mission today was to determine if the fishery could still support trout. Unfortunately bass were introduced to the lake so any trout that come into the lake from the tributary are quickly ate.
A common theme among mountain lakes is very poor water quality. Today was no different. The conductivity was 16 uS/cm which is incredibly low. An average middle Georgia pond usually averages 60-90 uS/cm. The lake’s visibility was 13 ft while a normal Georgia lake is 18 in to 5 ft. These conditions made electroshocking very challenging. Fish can see us coming plus the water does not carry electricity well. Even in the tributary where the fish were boxed in all we could do was watch the fish dance in front of the boat.
After a long investigation we determined that this lake has the capability to hold trout year around. We performed a dissolved oxygen profile to see if a thermocline has set up in the lake. To our surprise there was no thermocline thus allowing a suitable amount of oxygen throughout the water column. The water temperatures were 67 degrees at the surface and 63 degrees near the bottom. These are ideal conditions for trout. The main concern with trout in this lake is stocking them big enough so the bass can’t eat them. This fall we will stock the lake heavily with large brown trout and rainbow trout. Since the lake lacks fertility feeders will be set up to help supplement the trout’s diet.
New projects like this are what we love to do at AES. Although warm water fisheries are our main venture we have people qualified to assist in cold water fisheries.
