20 year Oakdale Canal near Knights Ferry 11301000 _ 20 year South San Joaquin Canal 11300500 _ 10 year Oakdale Canal near Knights Ferry 11301000 _ 10 year South San Joaquin Canal 11300500 _

These 10 and 20-year moving averages of annual diversions from the two canals below the Stanislaus River rim dam indicate that WY1975 may be used as a cutoff date. Before that date, diversions were steadily increasing independent of WYT or SJVI.

Lastly, USGS Records for Northside Canal at Merced Falls, CA (11270800) only exist from WY 1987-1994, so I would recommend using the entire period of record.
