Flood Impacts & Photos Collapse
13 Record flood disaster in the Mason Valley-Yerington area. Numerous homes...businesses...structures... roads...bridges and over 4000 acres of farmland and pasture are flooded with major damage. At about 4150 cfs...worse than record flood of January 4 1997...which flooded over 3000 acres in the Yerington area...with over 500 businesses and homes affected. USGS estimates that this much flow has about a one in 35 chance of being exceeded any year.
12.5 Near record flooding in the Mason Valley-Yerington area. Homes...businesses...farmland... pasture ...roads...bridges...and structures in the floodplain are flooded. At about 3700 cfs...about like record flood of January 4 1997 (est. 3900 cfs)...which flooded over 3000 acres in the Yerington area...with over 500 businesses and homes affected. Central Yerington and airport were not flooded in 1997. USGS estimates that this much flow has about a one in 25 chance of being exceeded any year.
12 Major flooding in the Mason Valley-Yerington area. Many homes...businesses...structures...roads...bridges and well over a thousand acres of farmland and pasture near the river flood. Some portions of Yerington flood. About 3300 cfs...exceeds flood of July 11 1995...but not as severe as record flood of January 4 1997. USGS estimates that this much flow has about a one in 20 chance of being exceeded any year.
11.6 Major flooding of lowlands with significant damage to farm and pasture throughout the Mason Valley-Yerington area. Structures adjacent to river in floodplain have damage if not sandbagged. Many levees leaking...and failures are possible. Diversion dam north of Yerington in danger of failure. Flooding of many secondary and some primary roads occurs. About 3000 cfs...like flood of July 11 1995. USGS estimates this flow has about a one in 15 chance of being exceeded any year.
11.3 Moderate flooding of lowlands with damage to farm and pasture lands throughout the Mason Valley-Yerington area. Some low structures adjacent to river have flood damage. Levee and diversion structure failures are possible. Several secondary and some primary roads flood. About 2800 cfs...Like floods of July 11 1995 and June 19 1983.
