    If American waterways had ever been voted on the yearbook，the Buffalo River could easily have been named Ugliest.It could be hard to find hope there.It took decades for public perception of the river to shift.But activist citizens，who collaborated with industry，government，and environ-ment~groups.never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighring for.And by now the cleaned—up water is one of Buffalo’S biggest attractions.

By the 1960s，the river was seen as one of the worst sources of pollution pouring into the Great Lakes.The Buffalo River had caught fire many times.The surface had an oily layer，and any fish caught there were not eatable.

The waterway’s fate started shifting in the mid-1960s.Stanley Spisiak was a local Polish—American jeweler by day，but by evening he was the kind of guy who’d chase down dumpers(垃圾车)he spotted on the Buffalo River.By 1966 he found himself winning the National Wildlife Federation’s“Water Conservationist of the Year”award.And before long he got a nickname:“Mr.Buffalo River.”But there was only so much he could do—the river was still declared biologically dead in 1969.

Jill Spisiak Jedlicka is his great-grandniece.She picks up where he left off by directing the river’s protector organization，Buffalo Niagara Waterkeeper.Professor Schneekloth and seven friends founded the organization as an all-volunteer nonprofit in 1989，after organizing the first river cleanup that year.Today the group employs 27 full-time workers and has helped oversee the Buffalo River’s $100 million restoration.

So far，the Buffalo River’s water quality has restored，but it is still an ongoing issue，as sewage(污水)can overflow into the river after storms.Habitat restoration continues as well；fish and plantings are still being sampled to measure how well it’s gone.
