Bryant Spring is near the headwaters of Bryant Creek, about six miles north of Ava and just west of Highway 5. The flow from Bryant Spring marks the beginning of the Bryant as a perennial (always flowing) stream.
The spring is small compared to other major springs in the watershed. Its average flow is around 1.1 cfs (cubic feet per second), or 711,000 gallons a day. That was enough, however, to power a grist mill in years past.
Bryant Spring currently supplies water to a private fish hatchery. The old mill dam forms a pool that is used for fishing.
