Madison River Recovered From Whirling Disease

_Rainbow trout are rebounding in the Madison River, the world-class fishing stream where Montana's first known outbreak of whirling disease occurred about 15 years ago, devastating the rainbow fishery.
_

_In the 1990s, whirling disease slashed the rainbow trout population by 90 percent compared to levels measured in the 1960s and '70s.

_Now, after a succession of rebound years, rainbows under 10 inches have "pretty well recovered to pre-whirling levels" and the population of those larger is about 60 percent of what it was before the disease, said Dick Vincent, whirling-disease coordinator for the Montana Department of Fish, Wildlife and Parks until his retirement last winter.
