suggests that below-surface connections from elsewhere feed into Spring River. The low-flow discharge at the mouth of the river was measured at 210 cubic feet per second (5.9 m/s) on August 10, 1997, more than
Thirsty Creek alone could account for and more than half of the North Umpqua flow above Lemolo Lake.

Thirsty Creek is a perennial stream that flows on the surface upstream of Spring River but sinks underground about 0.5 miles (0.8 km) before reaching it. Even so, it appears likely to researchers that it is part of the same watershed and contributes to the Spring River flow. Evidence also
