The regional stream survey for northeastern Yukon (parts of NTS 106E, 106L, 116H and 116I) was conducted during the summer of 1995.

Field observations and analytical and statistical data are available for 36 elements in sediments from 304 stream sites, collected at an average density of one sample per 14.7 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are also available.
