Section 3.0 is a report on Trapper's drainage reconstmction efforts 1987-1998. It consists of a narra-
tive segment describing our reconstruction methods and results as well as a map showing the locations
of our drainage reconstruction efforts minewide. !n 1998, approximately 10,320 feet of drainage con-
struction work was performed in the Pyeatt and No Name drainages. Drainage repair work was
completed on approximately 26,900 lineaz feet of East Pyeatt, West Pyeatt, Johnson, No-Name, East
Buzzard, Oak, and Coyote drainageways during the 1998 field season.
Section 4.0 is the recontoured spoil sampling section. This section includes site specific spoil analysis
data and a map showing spoil texture and sample identification numbers for Ashmore pit only. No
samples were collected in Flintlock pit during 1998 as no regraded areas were completed.
Section 5.0 is a narrative and map showing topsoil stockpiles constructed in 1998 and proposed 1999
topsoil stockpile locations. Additionally, the map has been updated to show all existing topsoil
stockpiles minewide with appropriate identification numbers. The narrative and accompanying Table
5-1 describes topsoil stockpile locations, size and approximate volumes.
Section 6.0 is the stock tank and dozer basin section. This section comains a nazrative and a map of
stock tank and dozer basin locations. Table 6-1 reflects the revised as-built stock tank density.
