Oldham Lake boasts exceptionally clear water, which can make fishing a little more challenging. Oldham lake has good numbers of crappie and bluegill. The bigger bluegill are around 7.5- to 8-inches and can be found along the shore on nests during the spawn. The nests will be close to shore due to the steep sides of the ponds and the narrow band of shallow water around the pond. The majority of the harvest size crappie are around 8- to 10-inches. The largemouth bass population is fair. Channel catfish are stocked on a regular basis.(2020)
