Introduction How Rivers Run Stories Value Of A River What We Can Do
Restoring Ups and Downs on the Mississippi
(pg 9 of 11)

The Mississippi has improved in other ways in recent years. The river was nearly an open sewer during the early and mid 20th century. But water has become much cleaner as cities along the river's shores have improved sewage treatment and separated storm and septic sewers to prevent the contamination of stormwater with human waste.

With cleaner water, some aquatic life has made a remarkable comeback. Pool 2, stretching from St. Paul to Hastings, now provides good fishing (though fish consumption advisories warn against eating fish frequently). Mayflies, once rare in the polluted sediments of the pool, have returned, sometimes emerging in spectacular "hatches" of such numbers that snowplows have had to clear highway bridges of their spent bodies.
