B. SPECIFIC GUIDELINES 



1. Specific Guidelines for Scraped Sites 



a. Distribute coarse gravels or cobbles, when available, over the 

 surface of the gravel removal area, to provide for a more rapid 

 rearmoring of the surface 



b. If the low-flow buffer was disturbed, return it to its natural 

 configuration and height 



c. At side channel sites which were diked to work in a dry con- 

 dition, remove the downstream dike and lower the upstream dike 



to a level corresponding to the river stage of a 1.25-year flood. 

 This will prevent large quantities of sediment from being washed 

 from the site into the river at low-flow conditions. 



2. Specific Guidelines for Pit Excavated Sites 



a. Overburden and vegetated slash and debris should be: 



• Broadcast or piled, or both, in the nonflooded portions of 

 the mine site, including islands and shorelines 



• If any material remains, some may be placed in the flooded 

 portion of the site to provide nutrients and cover 



b. Slope and contour shoreline banks and all overburden stockpiles 

 in nonflooded portions of the mined area to provide naturally 

 appearing configurations that blend with surrounding features. 

 These procedures should provide and maintain those characteris- 

 tics of diverse shoreline configurations and profile, bank slope, 

 and water depth as discussed in previous operation guidelines.
