Northern Nevada is set to experience the warmest weekend of 2026 so far, with officials warning that the Truckee River remains dangerously cold. Experts warn that spring conditions can make the river colder and more hazardous than it appears. The Desert Research Institute's Division of Hydrologic Sciences, Mark Hausner, said the average water temperature at the beginning of May is about 50 degrees. Officials have recommended that anyone seeking a cool dip in the river should take extra precautions, including wearing head protection and personal flotation devices. They also warned that the river may contain sharp objects such as glass that can injure feet.
