Starting Wednesday, Aug. 12, 2015, biologists will drip non-toxic green dye into the headwaters tributaries of Soda Butte Creek. During the rest of the week, they will drip non-toxic green dye into the lower reaches of the creek, as far down as Icebox Canyon – just above its confluence with the Lamar River in Yellowstone.
The dye will help biologists test and understand the flow, volume and currents in the Soda Butte Creek drainage.
Starting the week of Aug. 24, biologists and technicians from state and federal agencies in Montana and Wyoming will all treat all creeks in the drainage with a piscicide to remove non-native brook trout. The project is designed to conserve native Yellowstone cutthroat trout in the drainage and prevent non-native brook trout from spreading into the national park.
An environmental assessment of the project was completed in July.
Before the treatment, biologists will capture native Yellowstone cutthroat trout from the creek and house them in clear water. After the treatment, the fish will be released back into the Soda Butte Creek drainage.
The project is a cooperative effort between Montana Fish, Wildlife and Parks; Gallatin National Forest; Shoshone National Forest; Wyoming Department of Fish and Game and Yellowstone National Park.
