Nevada Department of Wildlife spokesman Chris Healy says they'll begin releasing the first of 35,000 trout into the Truckee River Thursday morning at Fisherman's Park just east of downtown Reno.
NDOW biologist Kim Tisdale says it's four to six weeks earlier than usual but is necessary to make sure there's still enough water in the river to support the fish before flows are expected to dwindle early this summer.
Tisdale says if they don't act now, they'll end up with a hatchery full of fish and nowhere to put them.

The City of Sacramento Department of Utilities reports Friday that city water customers saved more than one-billion gallons of water last month.
