Holter Dam raised the water level behind it by about 100 feet (30 m), creating the 24-mile (39 km) long Holter Lake (also known as Holter Reservoir).
Holter Lake has a surface area of 4,800 acres (1,900 ha).
The lake has a mean depth of 50 feet (15 m) and a maximum depth of 121 feet (37 m).
Holter Lake stores 243,000 acre feet (300,000,000 m³) of water when full.
The distance between Hauser Dam and Holter Lake is 4.6 miles (7.4 km).

The Missouri River runs free for 90 miles (140 km) between Holter Dam and the five dams at Great Falls, Montana.
