intersex fish in the potomac river?

i am a huge fan of stephen colbert...part of the colbert nation, if you will. i was completely disgusted with the so-called environmental protection agency (again) after watching the interview with new york times columnist nicholas kristof. apparently usgs scientists found prolific occurances of intersex bass, 82% of small mouth and 23% of large mouth, in the shenandoah and potomac rivers. that is repulsive. does the epa actually do anything? does anybody else think this is unacceptable? i think i will continue to catch-and-release.
