Surface Water Hydrology - Rules 2.04.5, 2.04.7, 2.05.3(4), <br />Information pertaining to surface water hydrology may be found in Section <br />2.04.4, 2.04.21, 2.05.11, 2.05.31, Volumes 1, 2, 3, and 4 of the Permit <br />Revision No. 2 application. <br />Deep Canyon, in the Revision No. 2 permit area, is drained by Deep creek, <br />an intermittent, ephemeral stream. Deep Creek is tributary to <br />Stollsteimer Creek near the northwest corner of the revision boundary. <br />Deep Creek normally sustains flow from early spring through July, at <br />which time the creek may become intermittent. High flows in the creek <br />are usually in response to spring snowmelt and intense summer rains. <br />These summer rains have been observed to cause flash flooding in nearby <br />canyons. The greatest discharge measured in Deep Creek was about 7 cfs <br />in 1983. <br />No known permanent structures dam Deep Creek, and no known water for <br />irrigation is taken from the creek. <br />Stollsteimer Creek, above its confluence with Deep Creek, flows through <br />the northwestern corner of Permit Revision No. 2 area. Stollsteimer is a <br />perennial stream whose flow varies seasonally. Highest discharges occur <br />during snowmelt and in response to intense rain storms. Discharges <br />approaching 300 cfs have been measured on Stollstiemer Creek. Water from <br />Stollsteimer Creek is used for flood irrigation both up and downstream of <br />the mine site. Water from Stollsteimer Creek is also diverted to fill <br />Capote Reservoir, about 5 miles upstream from the Chimney Rock Mine. <br />
