Panda Diversion Channel Monitoring Program, Data Synthesis 1998–2001, Technical Report Draft, Ekati Diamond Mine (BHP Billiton, September 2002)
1 September 2002Report
This technical report synthesizes and analyzes hydrologic, benthic invertebrate, periphyton, and fisheries data collected from the Panda Diversion Channel Monitoring Program from 1998–2001, evaluating the effectiveness of the constructed compensation channel that maintains fish passage between North Panda and Kodiak Lakes at the Ekati Diamond Mine. The report presents streamflow hydrographs, rating curves, habitat assessments, and biological community analyses to support future management decisions for the channel through 2007.
