Stanislaus River Flows

Looking for information on the flows on the Stanislaus River? Read on to get current conditions as well as future projections for flows on the Stanislaus River. July 1st and later we should see commercially raftable flows, that are still above normal flows.

A guide to flows on the Stanislaus River:

-Flows are measured in cubic feet per second (CFS).
-Average flows on the Stanislaus in summer months are somewhere between 250-750CFS. These flows are, under most conditions, considered amateur-friendly “float trips”.
-Flows between 750-1000CFS are still fairly mellow, but we do recommend participants know how to swim, and you want to have one adult per child attending.
-Flows between 1001-1300CFS are slightly more challenging, and require at least 2+ strong paddlers per boat, and we recommend all participants know how to swim.
-Flows between 1300-2000CFS are considered high flow. At this point 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 “un-runnable”, except for in specific scenarios (certain sections of the Stanislaus are runnable at these flows, but we do not recommend the general public raft above 2000CFS without extensive planning).

Flow projections for 2017

September 6th to September 24th flows will be in the 400CFS range, which is a mellow, summertime average flow!

September 23rd and 24th (our last weekend) flows will be back around 400CFS.
