FISHING -- After weeks of shutdown because of a fish-killing parasite, Montana Fish, Wildlife and Parks reopened the upper stretch of the Yellowstone River and its tributaries to fishing today – from the border of Yellowstone National Park to the Carbella Fishing Access Site.

"Recent surveys show this stretch has not experienced additional fish mortality since the department moved to open it to non-angling activities last week," the agency says in a release.

However, the section of the Yellowstone from Carbella Fishing Access Site downstream to Highway 89 Bridge Fishing Access Site remains closed to all use. FWP continues to see some dying fish in portions of this reach.

Montana closed 183 miles of the river and tributaries on Aug. 19 as tens of thousands of fish were dying from complications caused by an invasive parasite.

The closure was eased somewhat last week.

"FWP will continue to monitor Yellowstone River conditions, and take into account fish mortality and test results when making decisions as to any changes in closure status," the agency said.
