Intensity of water quality sampling on four major Wisconsin tributaries was increased to provide data for the International Joint Commission, Upper Lakes Reference Group project entitled 'Land Source Inputs to Upper Great Lakes From the U.S.'. Involved were (1) analysis of water samples from fixed stations on a monthly basis, (2) increased sampling during spring runoff and sampling for an expanded list of parameters three times during the year, and (3) an intensive survey run twice on each river during the summer of 1974. With the exception of localized problems, the data indicates that Lake Superior water off Wisconsin tributaries is of excellent quality and supports diverse and abundant populations of aquatic organisms
