SECTION 3.0 2005 Drainage Reconstruction, Improvement and <br />• Repairs at Trapper Mine <br />3.1 Drainage Reconstruction 1987-2005 <br />At Trapper Mine, all or portions of six major drainageways (Coyote, Johnson, Buzzard, No-Name, Flume <br />and Pyeatt) and their tributaries have been regraded and appropriately treated to reduce the erosion rate <br />and assist in permanent channel stabilization from 1987 through 2005. At the conclusion of the 2005 <br />field season, approximately 86,500 linear feet (16.38 miles) of permanent drainage reconstruction had <br />been completed at Trapper Mine (Map 1). No new drainage reconstruction was performed in the 2005 <br />season. <br />3.2 Drainage Improvements and Repairs <br />Improvements and repairs were performed to provide benefits to all drainages treated in 1987-2005 as <br />well as portions of undisturbed and disturbed drainage segments. Drainage improvements include dozer <br />basins constructed in newly stripped topsoil areas and on newly regraded spoils. Drainage repair and <br />enhancement was completed on approximately 1,800 linear feet of drainageways (No-Name, Pyeatt, <br />Flume and Oak drainages) during the 2005 field season. <br />• BON 3/06 <br />~DMG~DSGPoetl3-17 <br />• <br />
