The regional stream survey for Iskut River, British Columbia (NTS 104B) was conducted during the summer of 1987.

This report presents analytical and statistical data for 20 elements in stream sediments from 661 sample sites, collected at an average density of one sample per 12.5 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

Other information:

Gold usually determined on 10-gram sample, allowing a detection limit of 1 ppb; sample weights less than 10 grams resulted in a detection limit of 2 ppb. Sample weights less that 5 grams not analyzed.
