"The ground water resources of the Sugarloaf Mountain subdivision were investigated by reviewing the available literature, conducting on-site drilling and field testing, and analysis. The proposed subdivision covers approximately 4 square miles lying in Township 2 North, Range 11 West (T02NR 11W), sections 26, 27, 28, 33 and 34. The geology of the site consists of volcanic flows and ruffs separated by volcaniclastic sedimentary units, both of which are overlain by younger gravelly sediments. Groundwater is found in the volcaniclastic sedimentary units of the middle spears Group (units Tsa and Tsb). Geologic structures have little if any impact on the area hydrology. The testing performed indicates the chief structures have little if any impact on the area hydrology. The testing performed indicates the chief aquifer in this area has hydraulic conductivity (K) of about 0.6 feet per day (ft/d), consistent with the literature and with nearby tests of the same aquifer units. The middle Spears Group aquifer (unit Tsa and/or Tsb) is believed to extend beneath the entire study area with saturated thickness in excess of 100 feet. Depth to water is expected to range from 150 to 600 feet, and typical well yields should range from 1 to 3 gmp. No dry borehole conditions have been reported though they may exist. Modeling predicts that production of groundwater to meet projected demands for the next 20 years is feasible without dewatering the aquifer. Groundwater temperature is warm (perhaps sixty to seventy degrees Fahrenheit), and preliminary groundwater analyses of water samples indicated the groundwater quality is very good."--Executive summary, p. 1.

"This Geohydrologic Investigation Report (GIR) was prepared to describe the groundwater resources of the proposed "Spring Canyon" subdivision (study area), a Type 2 subdivision located about six miles southwest of the town of Quemado in Catron County, New Mexico (Figure 1). The proposed subdivision is to consist of 166 lots in sections 26 and 35 of Township 1 North, Range 17 West. The total area of the proposed subdivision is 843 acres, with an average lot size of about 4.8 acres. The water supply plan proposes a community well, pending approval of the Water Right Application by SEO. Alternatively, shared wells will be used for the water supply, each well serving 6 lots. In either case, withdrawals will be limited to 0.35 AFA per lot and the total groundwater withdrawal for all 166 lots is therefore 58.1 AFA, or an equivalent rate of 36.0 gpm."--Introduction, p. 1.
