The Iowa River was declared “the third most endangered river” in the United States this week by American Rivers. Iowa’s failure to enact strong “anti-degradation” policies, especially those that curb silt and pollutant run-off, are named as the key reasons water quality in the Iowa River is bad and getting worse.

As an aside, I remember a guy I talked to below the Burlington Street Dam in Iowa City. Upon learning I was from Minnesota, he explained to me that the Iowa River was a “natural, healthy river” compared to what I knew in Minnesota. He claimed no regulation of water quality was needed, since the Iowa was in such good condition. Having grown up around rivers and streams in which water clarity was measured in feet rather than centimeters, I was too stunned to really say much. That doesn’t happen very often. I should have offered him a glass of clean, healthy, brown Iowa River water, complete with the raw sewage run-off that comes from Fairfax via Clear Creek.
