Gauge Information

Gauge Description:

Boating on the Tuolomne can be divided into two seasons: Spring spill season and Summer powerhouse release season. The spring, high flow season can have very high flows that are suitable for only the most-skilled paddlers. Commercial rafting trips rarely begin above 8,000 cfs. 6,000 cfs is considered an above normal flow, and 3,000-4,000 cfs is considered a very good flow. Once spills from Hetch Hetchy & Lake Eleanor cease, flows are around 1,500 cfs or less. During non spill, flows are a combination of powerhouse outflow from Holm Powerhouse on Cherry Creek, and a minimum release into the Tuolumne River from Early Intake diversion.

The flow from Holm Powerhouse takes a few hours to reach Meral's Pool.

Inflows to New Don Pedro Reservoir will be mostly the flow from the river, although there are some low elevation creeks that can have a large effect during the winter.   Inflow is reported as a 24 hour average after midnight.
