Collection of terrestrial invertebrates was conducted at all fish 

 intensive sites and at the regional representative sites. Collections were 

 made adjacent to the watercourse at the disturbed site and near the upstream 

 aquatic sampling station to assess the availability of potential food 

 sources for the aquatic environment. Sweep nets were used to collect inverte- 

 brates. Specimens were preserved in 40 percent alcohol and returned to 

 the laboratory for identification. 



DATA BASE 



The data base, the third end product of the gravel removal study, 

 (the Technical Report and Guidelines Manual are the first two end products) 

 consists essentially of all information collected during site selection and 

 field data collection. Information for each of the 25 study sites includes: 



• Case history information including mining plans and permits, if avail- 

 able; 



• Biological, hydro I ogica I , and water quality field data; 



• Geotechnical evaluations; 



• Tabulation of data summations; 



• Computer printouts for aquatic ecology and hydrology and hydraulics; 



• Draft site description reports; 



• Site photographs, including both ground and aerial; 



• Topographic maps showing site location; and 



• Depiction of actual data collection areas within each site.
