1. An access r•ozd will be constructed from an existing access gate located
on Highway 13 to. the pond location. The road will be approximately 550
feet long'and 20 feet +aide. It will be constructed approximately level
with the existing ground surface to avoid the possibility of impounding
water if Good Spring Creek rose out of its banks. A culvert will be
utilized as a temporary crossing zt Good Spring Creek. FoiTo+ving comple-
tion of construction, the crossing will be removed. The same procedure
will be incorporated for crossing during future dredging operations.
2. vegetation will be removed from the area and a key cut made as shown in
Figure 2.
3. The pond will be excavated to design elevations shown on Figure 1.
4. Excavated material will be placed into the dam configuration in successive
Tifts to ensure a minimum of 90ro compaction.
Operations Plan
5. Outlet structures and protection will be constructed as shown in Figures
1 and 2.
6. Following completion of construction, the area will be prepzred for and
