History
Pactola Dam was built in 1952 by federal authorities to provide Rapid City with a new water supply, following the related construction of Deerfield Dam in 1945.[3] The new reservoir inundated the mining town of Pactola,[4] and construction was completed in 1956 after the movement of more than 4.3 million cubic yards of embankment fill. Severe thunderstorms in 1972 that caused flooding in Rapid City led to dam modifications to ensure safety, with further safety modifications in 1987.[2]
Ecology
Many fish live in Pactola Lake, including lake and brown trout as well as perch and bass.[1][5] An invasive zebra mussel infestation was detected in the summer of 2022.[6][7]
Recreation
Visitors can go boating, camping, swimming, and hiking.[1] The lake is popular with fishermen, and scuba divers can see the limited remains of the town of Pactola.[5]
