Gjevillvatnet[2] is a lake in Oppdal Municipality in Trøndelag county, Norway.

Water is tapped from the bottom in the western part of the lake, for use in the Driva power station.

This river now mostly runs dry every year due to the dam on Gjevillvatnet, and the trout are almost non-existent in the watercourse.

Along the middle of the lake, lies the Gjevillvasshytta, a lodge owned by Trondheim Turistforening.

Here guests can eat, sleep, and use the lodge as a starting point for walking trips in the Trollheimen mountains.
