Stanislaus River Flows
What are the flows in 2023?
The short answer is: we don't really know! Reservoirs were low heading into 2023, but well above-average rainfall could change that.
In general, year-to-year, flows are normally "high" in May and the first half of June, more middle-of-the-road in late June, and then average in July, August and September.
Do note that flows can change dramatically overnight. This section of river is 100% dam controlled, so flows can increase or decrease based on the needs of local and state water quality requirements.

A Guide to Flows
- Flows are measured in cubic feet per second (CFS).
- Average flows on the Stanislaus in summer months are between 200-749CFS. These flows are considered amateur-friendly "float trips".
- Flows between 750-999CFS are still mellow, but we do recommend participants know how to swim, and you want to have one adult per child attending.
- Flows between 1000-1299CFS are more challenging, and require at least 2+ strong paddlers per boat, and we recommend all participants know how to swim. Alcohol is not allowed.
- Flows between 1300-1999CFS are considered high flow. Participants need to know how to swim, all boats need 2+ strong paddlers, and strong communication among group members is a must. Alcohol is banned at these flows. All children must be 7 or older.
- Flows above 2000CFS are normally too dangerous to run trips. We do not recommend the general public raft above 2000CFS.
