Document Description
Glenn-Colusa Irrigation District (GCID) may not have adequate surface water supplies to meet irrigation demands from November 1, 2008 through October 31, 2009. To address this potential shortage, GCID needs to immediately begin the development of a groundwater pumping program with GCID landowners/well owners to pump groundwater and make it available to GCID for distribution to all landowners within GCID. GCID estimates that 45 to 60 wells will be required to meet the forecasted shortage. The candidate wells have well casing perforations ranging from 30 to 50 feet below ground surface elevation (bgse) to a depth of 350 to 450 feet bgse. This range of perforation elevations indicates that these wells will be producing water from the Tehama Formation. Average yields from this aquifer range from 2,500 to 3,000 gallons per minute. Based upon the projected surface water supply shortages, GCID will need up to 160,000 acre-feet of groundwater to meet the total water supply shortage. This amount of groundwater is still less than the 180,000 acre-feet of water that GCID recharges to the aquifer system on an annual basis during non-critical years. Therefore, any groundwater pumped during this project will be recharged during the next year that GCID receives 100% of its surface water supplies, which occurs in nine of every ten years.
