Problems/Comments
Dam blow-out of 60 million gallon water reservoir carrying mining tailings into Valdez Creek floodplain. Same dam had a second blow-out on May 25, 1992. Resulting in a loss of 15 million gallons of processed water into floodplain. The mining tailings were re-deposited (had been previously pulled back from stream after first blow-out). Concern of metals, turbidity and settable solids adversely impacting stream (Extensive effort in winter of 1991 to construct a stream diversion channel which Fish and Game required a fish catching basin be installed to capture Grayling for manual transportation up river for stream diversion). Last staff assigned was Wien.
