It's going to be hot this weekend, and if you think your might take a dip in the Truckee, N-Dot's Stormwater Program and the Reno Fire Department have a message for you. They've teamed up for a new Public Service Announcement saying trash, glass and other hazardous materials dumped into the Truckee River not only pollute, but are also safety hazards. Deflated flotation devices, litter and debris can entangle a swimmer, and glass and other hazardous materials can cause injuries. Reno Fire Chief Dave Cochran and his team are part of that new video.
