Agenda - November 10, 2015
Both winter and summer of 2015 were wetter than in 2014, however, similar to last year, snow accumulation was well below normal across most of the state. While the drought appears to be easing, it is not over. More than two-thirds of the state is abnormally dry or in moderate drought, reservoirs are only approximately half full, and every Arizona county had a disaster designation during water year 2015. It will take several years of above average precipitation to break the grip of the drought that is approaching 21 years.
Strong El Niño conditions are currently in place and will most likely continue into the spring. This means there may be more rain and more rainfall days than usual. Mountain snowfall, however, may or may not be above average.
The current Colorado River reservoir system storage stands at 51% of capacity as of November 8, 2015, approximately the same as last year. The forecast shows a 0% chance of a shortage declaration in 2016 and an 18% chance in 2017. The Salt and Verde reservoirs remain at the same levels as this time last year, approximately 49% full.
Due to the moist conditions, water year 2015 was a light year for fires. However, the above average rainfall has resulted in an abundance of continuous fine fuels in general across the state which could potentially lead to a busy wildfire season, depending on weather patterns in late spring. Extreme fire danger continues to be a threat in forests due to the extreme density of trees.
The impact of drought on range and farmland resulted in disaster designations for all counties in the state. Drought conditions affected dryland farming and irrigation water supply resulting in crop loss, reduced rangeland water supply, and reduced forage supply.
Based on this information, the ICG unanimously recommended that both drought declarations be kept in place:
- Drought Emergency Declaration (PCA 99006) has been in effect since June 1999 and maintains the state’s ability to provide emergency response if needed. It also enables farmers and ranchers to obtain funding assistance through the Farm Service Agency if they experience production losses due to drought.
- The Drought Declaration for the State of Arizona (Executive Order 2007-10) was issued in May 2007 to raise awareness of Arizona’s continuing long-term drought and encourage conservation.
