Floods

Flash floods, abundant rain, and rain-on-snow events can occur throughout the area. In many places these events cause small creeks to overflow and homes in low-lying areas can experience some localized flooding. In addition, scientists have determined that an earthquake or landslide event into Lake Tahoe could trigger a seiche or series of lake waves much like a tsunami.

Before a Flood occurs:

Check drains and drainage to divert water away from your home. Build barriers and landscape around your home to reduce or stop floodwaters and mud from entering. Keep snow and ice cleared from drains.
Plan for evacuation including where you are going to go and the route you will follow.

During a Flood:

In the event of a seiche, remember that additional waves will follow the first one and may be even larger and more destructive.
Do not try to drive or walk through flooded areas. Water can be deeper than it appears and water levels rise quickly. If your car stalls in floodwater, get out quickly and move to higher ground.
Listen for updates from the radio and television. Know the location for sandbags and sand. Contact local authorities and notify them of the location of the flooding. If necessary, turn off utilities before problems escalate.

After a Flood:

Prior to entering a building, check for structural damage. Make sure it is not in danger of collapsing. Electrical power and natural gas or propane tanks should be shut off to avoid fire, electrocution, or explosions. Watch for electrical shorts or live wires.
Avoid floodwaters; water may be contaminated with oil, gasoline, or raw sewage.
Listen for news reports to learn whether the water supply is safe to drink.
Wash your hands frequently with soap and clean water if you come in contact with floodwaters.
