bottom. Land use is grazing and wildlife with mining as a <br />• minor use in the lower reaches of the canyon. <br />With similar conditions, the same conclusions frotr <br />Apache Canyon were applied to Ciruela Canyon. That is, Ciruela <br />Canyon does not contain an alluvial aquifer, subirrigation, <br />flood irrigation, or historic agricultural activity, and the <br />Division found it is not an alluvial valley floor based on size <br />criteria. <br />Santistevan Canyon lies to the northwest of the Golden <br />Eagle Mine. Drainage area of the canyon is 2181 acres <br />comprised mostly of woodland. The canyon is in the process of <br />being subdivided into 35 acre ranchettes. There are currently <br />four houses and a lodge with a swimming pool located in the <br />upper drainage. These structures utilize Trinidad City water. <br />Waste disposal is by means of septic systems and drain fields <br />which may supply additional water to the alluvial system. <br />• Three USGS springs have also been identified in the canyon and <br />appear out of fractures between sandstones and shales which ~ <br />outcrop on the surface. <br />As described for Apache and Ciruela Canyons, the AVF <br />study exhibits a similar situation. The canyon has a narrow <br />valley bottom consisting of shallow alluvial material. <br />Available water is limited and associated with bedrock outcrops <br />and canyon constrictions. As such, no alluvial aquifer has <br />been identified. In addition, no subirrigation, flood <br />irrigation, or historic agricultural activities exist in the <br />area to be undermined. <br />Section 2.04.7 of this document notes that Lopez Canyon <br />has a drainage area of 860 acres. Land use is grazing and <br />wildlife habitat. Data collected from the surface water <br />station at the mouth of the canyon (Annual Hydrology <br />• Reports)indicates no surface flow. <br />2.05-46 (Revised 04/27/94) <br />
