Summary of Cropping Patterns and Irrigation

The crops grown within the Klamath Project area consist of grain, hay, pasture, silage, mint, potatoes, onions, vegetables, alfalfa, and horseradish.  This list of crops represents the majority of crops grown within the Klamath Basin over the last 40 to 50 years.  The cropping pattern has varied from year to year, but the overall planted acreage has remained consistent.   

Irrigation water requirements from the Klamath River are diverted and measured at the A Canal, Station 48, Miller Hill Pumping Plant, North Canal , and Ady Canal .  The unmeasured sites include Number 1 Drain, miscellaneous private diverters along the Lost River diversion channel, and diversions made from Spring Lake .  The following plot shows the combined volume for all diversion points from the Klamath River .  This plot includes an estimate of the diversions made at the unmeasured locations.  As can be seen from the plot, diversions from Klamath River have remained relatively consistent between 400,000 and 550,000 acre-feet during March through October, with the exception of 2001 when curtailments by the Bureau of Reclamation were made to Project water users.
