Title
SPDSS Task 69 - Estimate Reservoir and Stock Evaporation
Description
The purpose of Task 69 is to estimate the capacity of smaller, non-key reservoirs and stock ponds, combine them by Water District into “aggregated” reservoirs, and estimate their evaporative losses.

Livestock Tank: is constructed for livestock watering and may not be used for <br />irrigation. The dam must be less than 15 feet high and have a capacity no greater than <br />10 acre-ft. <br />Erosion Control Structure: is constructed to control erosion and must be built in a <br />channel that is normally dry. The dam must be less than 15 feet in height and less <br />than 10 acre-ft in capacity. <br />The 3,200 structures are classified as either livestock tanks or erosion control structures. <br />Although many of the dams listed are greater than 10 acre-ft in capacity, all but four of them <br />are within the 100 acre-ft capacity limit established for non jurisdictional dams. <br />2. As discussed above, only reservoirs with decreed volumes less than 30 acre-feet were <br />included with the stock pond analyses. HydroBase was queried using StateView to show <br />water rights in Division 1 and Water District 47 associated with reservoirs (water rights <br />structure code 3) with decreed volumes less than 30 acre-ft. The use-type codes from this list <br />of storage rights were checked to ensure that they had decreed livestock uses (code STK). All <br />of the rights had use codes that included livestock uses and 30% of the structures were <br />decreed for only livestock use. Note that non jurisdictional structures do not have decreed <br />water rights, so there is not the potential for double-accounting storage. <br />3. Reservoirs with decreed volumes less than 30 acre-feet and non jurisdictional structures were <br />combined and the tank capacities and decreed volumes were aggregated by Water District. A <br />10-foot depth was used to convert volumes to surface area. The results appear in Table 5. <br />Page 9 of 14 <br />
