The Smithers (NTS 93L) reconnaissance-scale stream sediment and water survey was completed in 1986 and the resulting field and analytical data were released in 1987. A total of 900 sediment and 878 water samples were collected from 850 sample sites. The survey also included the collection of lake sediment and water samples from 243 sites. |
