Measuring at around 3,500 acres (14 km2), it is the largest lake in Indiana built completely above ground, its shores consisting of rock levees on all but two of the lake's six sides both of which were also built up to build the power plant. Opened to fishing in 1978, Gibson Lake had been a prime source of bass and several types of catfish, bluegill, and carp."@en . . "2.68764e+07"^^ . "Gibson Lake"@en . "2414.02"^^ . "9656.06"^^ .
