Maggie Creek is a southward flowing 85.4-mile-long (137.4 km)[3] stream that begins in the Independence Mountains and is a tributary to the Humboldt River in Carlin in Elko County in northeastern Nevada.

[citation needed] Maggie and Susie Creeks, which enter the Humboldt River near Carlin, have benefited from 20 years of work by ranchers, agencies, mines, and non-profit groups via improvements in grazing techniques and specific projects.

These projects, which include installation of fish passable culverts, have led to the return of migrating Lahontan cutthroat trout (LCT, Onchorhynchus clarkii henshawi).

Maggie Creek was assumed historically to support an interconnected "metapopulation" of LCT where fish accessed tributary and mainstem habitats needed for growth, gene exchange, spawning migrations, and refuge from stressful conditions.

[12] North American beaver (Castor canadensis) seem to have been making a comeback in Elko County possibly due to less fur trapping combined with reduced consumption of riparian willow and other vegetation by cattle.
