Stored water is measured in acre-feet (AF).

The amount of water delivered to your headgate or point of diversion is measured in cubic feet per second (cfs).

1 cfs = 1.98 AF per day

Include Transit Loss:

CDWR requires that stored water contract deliveries include transit loss of 0.16% per river mile. For example, if you ordered 1 cfs of water from Stagecoach Reservoir to be delivered to a diversion at the James Brown Bridge in Steamboat (50 river miles):

1 cfs = 1.98 AF/day

Total Transit Loss = 0.08 AF/day (for 50 river miles)

CDWR Protected Delivery to Diversion: 1.98 – 0.08 = 1.92 AF/day = 0.97 cfs

Transit loss varies depending on diversion distance downstream from reservoir.
