Note 1: Data represented in the files are in kcfs (thousands of cubic feet per second).

Note 2: Each location includes 44 ensemble members with the first column starting with year 1980 and the last column ending with year 2023. Each historical year is more meaningful beyond the first couple weeks when climatology drives the spread in the ensemble.

Note 3: On October 20, 2022 the Central Coast forecast group was split into two forecast groups (Salinas/Pajaro and South Bay) and the Southern California forecast group was split into two forecast groups (Southern California and San Diego/Inland).
