Seneca Lake at Geneva

The past week

What floods at each level

• 449.9 ft

  This is the approximate level of the 1% annual chance flood, otherwise known as the 100-year flood. Widespread flooding would bring catastrophic damage to properties along most of the lake shore.

• 449 ft

  Major flooding occurs. Water would inundate most properties along the shore, likely reaching residential and commercial structures in some areas. Travel near and around the lake would become nearly impossible. Severe erosion and damage to seawalls and docks is to be expected during days with strong winds. Boating is likely to be forbidden.

• 448.95 ft

  This is the record high level set on April 26, 1993 after the much above normal winter snow season and Spring rainfall.

• 448.85 ft

  This is the high water level from the June 25, 1972 Hurricane Agnes flood.

• 448.5 ft

  Moderate flooding develops. Water would inundate at least 50 percent of the properties along the shore. Some residential and commercial structures would be affected. Travel near and around the lake would become extremely difficult. Damage to seawalls and docks would occur on days with moderate winds. Boating restrictions are likely.

• 448 ft

  The lake at this level will flood normally dry areas along the shoreline which may include the flooding of paths or roads nearest the shore. Docks may be lifted and destroyed by moderate wind wave conditions. Seawalls may also be damaged by wave action. Boating restrictions are possible.

• 447.5 ft

  The lake level is high enough to lift and damage docks and cause shoreline erosion, especially during times of light to moderate wind driven wave action. No-wake boater restrictions are possible.
