Permitted livestock wells
Figure 8-7 shows the distribution of stock permits in the WBRB, permits issued before and after 2000, and TWE permits. Stock wells are located throughout the WBRB, including rural areas of the WBRB where groundwater is the sole reliable source of water. The distribution of stock permits shows a strong correlation with rivers and other surface drainages within the interior basins; most are completed in Quaternary and Tertiary hydrogeologic units. Many permited wells (primarily permits issued before 2000) are also located in the areas between larger drainages and along the uplands of the basins, and are completed in various hydrogeologic units ranging from Quaternary to Precambrian and including both aquifers and confining units. The depth vs. yield tables on Figure 8-7 show that by far the most groundwater permits are for depths of 500 feet or less and yields to 25 gpm for both total permits and permits since 2000. More than onethird of the permits for stock watering are coded or have no recorded depth (none of the TWE permits data include depth); 18 have coded yield information. Figure 8-7 also shows that, like wells permitted for domestic use, stock wells have been mostly permitted at relatively shallow depth within virtually all hydrogeologic units (including confining units) across a wide range of elevations within the WBRB, illustrating that useful quantities of relatively shallow groundwater can be found at most locations.
