Flood Modeling Maps

Modeling maps depicting suggested flood areas along the Carson River if uncontrolled water tops Lahontan Dam. Flood areas depicted by color at 1,000 cubic-feet-per-second (cfs) intervals from 2,000-5,000 cfs flowing over the dam into the Carson River. 

Blue is current non-flood 1,000 cfs in Carson River. 

Maps are large files, so we suggest zooming in to magnify a particular area. This is only modeling and many things can effect flow, including debris not accounted for through Lidar.
