SSJID Begins Season Conserving Water for 2016

by Laurie Greene, CalAgToday reporter

As the Stanislaus River watershed enters its fourth year of consecutive drought conditions,  South San Joaquin Irrigation District (SSJID)'s water supply may not last through the end of the 2016 irrigation season. Therefore, with the season starting on March 15, the SSJID Board of Directors unanimously adopted a drought conservation program on March 10th to reduce the quantity of water used for the purpose of conserving the water supply for the 2015 and 2016 irrigation seasons. The District adopted a strict water allotment of 36” because studies have shown that more than half of its irrigators use less than 36”.  Irrigators must determine how and when to use their allotment.

Along with the 36” limit, allotment transfers will be allowed. The general rule will be that growers can increase or decrease their water supply by transferring all or a part of the 36” allotment between land parcels, with some exceptions. A District application form will be required for transfers, and the deadline for applications will be May 10. Parcels in a single transfer agreement will not need to have the same owners. Only parcels located in the District territory are eligible for the water transfer program. Transfer agreements will be for one year only and will be irrevocable.

The Board has also established a 10-day rotation schedule.

Agricultural water deliveries will be cut off once their allotment is used. SSJID’s online bill payment and consumption history service, available on the SSJID website, will update usage daily; however, the information will be three days old. Season-to-date usage will be shown on each customer's monthly bill.

Basically, New Melones Reservoir, the source of SSJID’s water supply, is running out of water. The troubling pattern of long, warm dry spells between rain events in the upper watershed is continuing with the result of very little runoff into New Melones Reservoir when it does rain, as the ground and vegetation is so dry that it is soaking up all available moisture. Precipitation in the upper watershed has been 60% of normal since October 1, and has worsened: January was the driest January in history, and no snow fell below 8,500 feet of elevation in February. As the snowpack declines, the New Melones is expected to decline to “dead pool” in September.

The State Water Resources Control Board (SWB) has issued an advisory that Curtailment Orders for Junior Water Rights holders are possible, given the bleak storage levels in all of the reservoirs, including New Melones. There is not enough water in New Melones to meet the Bureau of Reclamation’s regulatory needs and the District’s hard cap of 225,000 acre-feet this year. Any additional inflow or any conservation saved from this year’s total of 225,000 acre-feet, potentially as much as 39,000 acre-feet, will count toward 2016 water needs, so stringent conservation measures in the District will be so important during 2015. Every drop of water saved this year may be needed in 2016.

The District understands this will be a serious hardship for many and will offer irrigator assistance. For more information, call SSJID at (209) 249-4600.
