Mining da quel momento è stato sporadico con alcune attività come recentemente come i tardi anni cinquanta e primi anni sessanta (3). Il più presto il cinabro mining era sotto- massa, ma la tecnica più recente è stata fossa aperta mining.

. Forest land use and streamflow in central Oregon. Forests and forestry Oregon Ochoco Creek Watershed Multiple use; Watershed management Oregon Ochoco Creek Watershed; Stream measurements Oregon Ochoco Creek Watershed. Mining since that time has been sporadic with some activity as recently as the late 1950's and early 1960's (3). The earliest cinnabar mining was under- ground, but the more recent technique has been open pit mining. An area of about 20 acres of open strip mining work exists in the Lookout Mountain vicinity. Otherwise, there have been no significant land disturbances, clearings, or water use for mining since the construction of Ochoco Reservoir in 1920. There has been recent prospecting for agates, jasper, and other semiprecious stones at scattered locations throughout the water- shed. No significant land disturbances have resulted from this activity. Grazing by cattle and sheep was another early use of the area. Unregulated grazing of large numbers was a common practice in the late 1800's and early 1900's. However, grazing records on National Forest land show grazing use by cattle or sheep to be quite stable since 1924, annually averaging about 933 and 3, 100 animals, respectively. Normal season of use is from about June 1 to mid-September. Table 2 shows the per- mitted numbers of grazing stock on National Forest and certain private lands. A resident mule deer population was estimated at 1, 500 animals through 1950 and 5, 000 in 1964. The watershed also supports a small, unestimated number of Rocky Mountain elk. Hunting is allowed and is one of the major recreational uses. Other recreational use in the watershed is quite diversified. Fishing, "rock-hounding, " camping, picnicking, sightseeing, hiking, and harvesting of forest products for pleasure are permitted and dispersed throughout the basin. Concentrated recreational use takes place mainly at Walton Lake Campground, Wildcat Campground, Ochoco Summit Campground, and White Rock Springs wher
