of Public Health and the Environment (CDPHE). Sneffels Creek near the mine alternates between <br />shallow wide sections and very narrow steep areas that are in small canyons of extremely high <br />energy. The stream drops from 10670 feet elevation at the upper edge of the permit to 10580 feet at <br />the bottom of the permit area, over a distance of 2400 feet, therefore the grade is approximately <br />3.75 %. A flume of steeper grade exists just south of the permit area before the Creek reaches <br />Canyon Creek and the Camp Bird Mine. From there, the combined flow meets the Uncompaghre <br />River at Ouray, approximately 5 miles downstream from the mine. <br />Picture G -1 below was taken in August of 2011 immediately after a thundershower of <br />approximately .3 -0.4 inches, showing that suspended solids can get high in Sneffels Creek, in spite <br />of a durable rock bed over most of its length. Water quality of Sneffels Creek and other surface <br />water features is described in the next subsection. <br />Revenue Mine August 2012 G -11 <br />
