MINNEAPOLIS (AP) – A state pollution official says the torrential downpours this month have washed nearly a year’s worth of sediment into the Minnesota River and its tributaries.
A Minnesota Public Radio report says the high-intensity rain led to excess storm water flowing into the river.
Pat Baskfield coordinates a statewide river-monitoring program for the Minnesota Pollution Control Agency. Baskfield says events such as the June storms can account for 80 percent of the sediment load that passes through the river in a year.
Baskfield says the rainwater washed phosphorus and other fertilizers from farms and river banks into the river. Now levels are as much as 10 times the proposed pollution limit.
