Some fish species are being documented for the first time in Minnesota, such as occurrences of black buffalo in 1990 and blue suckers in 1989. Paddlefish and lake sturgeon have returned to the Minnesota River Valley. In some tributaries, the American brook lamprey is returning. Scientists attribute these new discoveries and recoveries to water quality improvements, which resulted from addressing point source pollution as part of the Clean Water Act of 1972.
