2 Utah Climate and Water Report The purpose of the Climate and Water Report is to provide a snapshot of current and immediate past climatic conditions and other information useful to agricultural and water user interests in Utah. The report utilizes data from several sources that represent specific parameters (streamflow data from the United States Geological Survey, reservoir data from the Bureau of Reclamation, and other sources), geography including high elevation United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) Snowpack Telemetry (SNOTEL) data, and agriculturally important data from the USDA NRCS Soil Climate Analysis Network (SCAN). Data on precipitation, soil moisture, soil temperature, reservoir storage, and streamflow are analyzed and presented. These data analyses can be used to increase irrigation efficiency and agricultural production. As with all data and analyses, there are limitations due to data quality, quantity, and spatial application. The U.S. Department of Agriculture (USDA) prohibits discrimination against its customers. If you believe you experienced discrimination when obtaining services from USDA, participating in a USDA program, or participating in a program that receives financial assistance from USDA, you may file a complaint with USDA. Information about how to file a discrimination complaint is available from the Office of the Assistant Secretary for Civil Rights. USDA prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex (including gender identity and expression), marital status, familial status, parental status, religion, sexual orientation, political beliefs, genetic information, reprisal, or because all or part of an individual s income is derived from any public assistance program. (Not all prohibited bases apply to all programs.)

3 Climate and Water Information Soil Climate Analysis Network Soil Climate Analysis Network (SCAN) stations are primarily located on lowto mid-elevation, agriculturally important landscapes that maintain representative soils. Elevations range from 3, to 7, ft. The SCAN network provides real time soil moisture and temperature data coupled with additional climate information for use in natural resource planning, drought assessment, water resource management, and resource inventory. Stations are situated on non-irrigated, native soils, are remotely located, and collect hourly atmospheric and soils data that are available to the public online. In order to summarize SCAN data, the 35 sites in Utah are grouped by climate divisions (North Central, Northern Mountains, Uintah Basin, Southeast, South Central, Dixie, and Western). Explanation of soil water capacity definitions. Field capacity (FC) and wilting point (WP) are calculated in the laboratory for each soil horizon. The amount of water held between field capacity and wilting point is plant available. Visual explanation of soil water capacity definitions.

10 Utah Hydrologic Summary July 1, 213 Current Conditions Current runoff, as shown in the USGS graphic below, remains well below average for all natural flow points. There are 26 points that are flowing below 1% of normal. Points shown in green (near normal conditions) are primarily where reservoir releases keep stream flows higher. June precipitation ranged from % on Pine Creek near Fillmore to 12% on the Escalante and 21% on the Raft River. The statewide average was 8% of normal. Many sites in southern Utah have gone between 4 and 6 days without measureable precipitation and the entire state has gone well over 4 days since precipitation of any consequence. Soil Moisture is currently at the bottom of historically observed July 1 values across the entire state. Utah watersheds are dry and getting dryer. Reservoir storage is declining rapidly, near 67% of capacity across the state, down 6% from last month and 12% less than last year. Water shortages and restrictions are being implemented statewide. Those reliant on direct stream flow can expect shortages for the remainder of the summer and fall and those with reservoir storage are likely to experience significant cuts to allocations.

15 Range Conditions Current lower elevation range conditions can provide information to agricultural users relevant to fall and winter grazing. Poor forage production could mean Ranchers may need to procure supplemental feed or reduce herd numbers for the winter whereas good production could mean adequate feed and the possibility to expand. The examples given below represent the general observations of Range Resource Specialists taken from private lands in various locations across the state. Individual producers should assess their grazing lands, both public and private for forage production to make a more accurate assessment of their individual and specific conditions. 213 Range conditions for SW Utah (Garfield, Kane, Iron, & Washington counties). The short story is that rangelands in southwest Utah are in better shape than in 212, but just barely. Overall, production on rangelands in southwestern Utah is only slightly higher than in 212. Production measurements in June 213 show between 3% 5% of expected average production for the associated range sites, compared to 2% 4% in June of 212. The exception to this has been on sites where brush has been treated. On these sites, the production has approached, or exceeded, expected average production. Grasses and forbs have produced seed heads, though much reduced. In most cases, the seed heads are actually producing seed, rather than aborted, as most were in 212. In lower elevation areas, livestock water ponds are dry and soil moisture is very low. Higher elevation, mountain sites are rapidly drying, with very little water storage in ponds. Many of the smaller streams and creeks are going dry, or are no longer flowing below the upper reaches. The photos below illustrate the difference in production from 211 to 213. Garfield Co. Seeded Range: lbs/acre lbs/acre

16 lbs/ac Iron Co. 198 s chaining: 211: 5 lbs/acre 212: 261 lbs/acre 213: 335 lbs/ac partially grazed

17 Iron Co. Seeded Range: 212: 273 lbs/acre 213: 381 lbs/acre Kane Co: Seeded Range: 211: 283 lbs/ac 212: 38 lbs/acre

18 213: 42 lbs/acre In some limited areas that presumably had isolated precipitation events forage production is very good as in these photos from Kane County.

19 213: 18 lbs/acre. This is just ½ mile north of a range site with 81 lbs/ac this year illustrating the need to do accurate assessments of range conditions for specific sites to determine individual needs for the fall/winter grazing season. Jerimiah Armstrong, Range Management Specialist, NRCS Sanpete, Sevier, Wayne, and Piute Counties Rangelands in Sanpete and Sevier counties were fairly productive during the spring of 213. Forages in the semi desert and upland ecological zones received sufficient moisture during May and achieved typical growth for the month. Production slowed during June due to the dry conditions. Cool season grasses are now entering summer dormancy and will likely not produce much more forage until fall. The mountain ecological zone has produced good forage, but will need additional precipitation during the months of June and July to maintain average forage production. Sub irrigated meadows have remained dry and only produced about 3% of the typical spring production. Along with the dry conditions, grass hopper infestations have caused additional stress to meadows and rangelands throughout Sanpete and Sevier counties. Wayne and Piute county rangelands got off to a slow start due to the cool spring. Now that we are in mid June, the cool season grasses in the desert, semi desert, and upland ecological zones have begun to enter summer dormancy and will likely not produce much more forage this summer. Warm season grass production will be low if dry conditions continue. Springs and ponds throughout the semi desert and upland ecological zones are drying out and livestock producers may need to leave summer ranges early due to a lack of livestock water. The mountain ecological zone has produced good forage, but will need additional precipitation during the months of June and July to achieve average forage production. Water shortages and insects in all four counties continue to negatively impact hay production. With the supply of hay being low and the demand high, the option of feeding hay to compensate for unproductive winter ranges may not be

20 economically feasible. Producers that cannot water their hay fields enough to justify the inputs of another cutting may consider grazing the fields this fall and winter as an alternative to cutting. Jacob Owens Rangeland Management Specialist USDA/NRCS Manti, UT In Central Utah, the National Resource Inventory conducted this past week shows an estimated 8% production by shrubs and 5 8% by grasses due to the dry conditions. Most of the areas we looked at had not been grazed recently and did not have the added stress of moderate to heavy grazing added on to the climactic conditions. Things have pretty much dried out for cool season species. Kevin Williams, Watershed Coordinator, NRCS, USDA.

What is a Water Availability Index? The Water Availability Index (WAI) is an observed hydrologic indicator of current surface water availability within a watershed. The index is calculated by combining current reservoir storage with the previous months streamflow. WAI values are scaled from +4.1 (abundant supply) to 4.1 (extremely dry) with a value of zero () indicating median water supply as compared to historical analysis. WAI's are calculated in this fashion to be consistent with other hydroclimatic indicators such as the Palmer Drought Index and the Precipitation index. Utah Snow Surveys has also chosen to display the WAI value as well as a PERCENT CHANCE OF NON EXCEEDANCE. While this is a cumbersome name, it has the simplest application. It can be best thought of as a scale of 1 to 99 with 1 being the drought of record (driest possible conditions) and 99 being the flood of record (wettest possible conditions) and a value of 5 representing average conditions. This rating scale is a percentile rating as well, for example a WAI of 75% means that this years water supply is greater than 75% of all historical events and that only 25% of the time has it been exceeded. Conversely a WAI of 1% means that 9% of historical events have been greater than this one and that only 1% have had less total water supply. This scale is comparable between basins: a SWSI of 5% means the same relative ranking on watershed A as it does on watershed B, which may not be strictly true of the +4 to 4 scale.
