Description:   A field assessment was conducted to determine the effects of subaqueous tailings disposal discharged from the Benson Lake Coast Copper Mine into Benson Lake. A preliminary field study was undertaken that consisted of monitoring lake recovery from tailings disposal as well as mapping the lake's bathymetry. In addition it was explained that field assessments between 1967-1973 revealed that Benson Lake was devoid of benthic life because the entire lake bottom was covered with tailings. Furthermore, lake morphometry, staff & crest gauges as well as stream profile & discharge was described.
