• Groundwater Uses <br />General Area <br />Groundwater uses in the general and permit areas of the Colowyo mine are minimal and of <br />low volume. Questions were raised in the past concerning well yields within four miles of the <br />mine site. At that time the Colowyo Coal Company undertook a program to investigate <br />reported yields based on the Colorado State Engineer's records. <br />A search of the State's files revealed that only three wells within four miles of the mine site <br />have reported well yields of 50 gal./min. The remaining wells have reported yields of less <br />than 16 gal./min; most of the wells have reported yields of less then 7 gal./min. The well <br />yields were not £eld checked to determine actual use or rate of use. There are no wells that <br />have reported yields in excess of 50 gal./min. <br />Very little groundwater resource development has taken place in the Axial area. There are a <br />few relatively shallow, low-yield wells on or near the leasehold area that were dug for <br />domestic purposes. <br />Permit Area <br />Groundwater uses in the mine area are also limited due to the depth to water and its limited <br />overall availability. Colowyo has developed two wells on the mine area to supply a portion of <br />• the domestic needs. The two deep wells, Taylor Creek Nos. I and 3 are located in Section 33, <br />T4N, R93W, and in Section 4, T3N, R93W respectively. Taylor Creek No. 1, completed to a <br />depth of 825 feet in the Williams Fork Formation, produces 40 gpm with a static water level <br />of 110 feet. Taylor Creek No. 3, completed to a depth of 2,284 feet in the Iles Formation, <br />produces 20 gpm with a static water level of 135 feet. <br />The information collected from the Colowyo Mine area indicates that groundwater is very <br />limited, even to depths significantly below mining activities. This conclusion is supported by <br />the depths of the potable wells, Taylor Creek No. 1 and Taylor Creek No. 3, necessary for <br />sustained production.
