Highlights of Washington County's Hazards Analysis and History of Disasters:

• Washington County Tornadoes map
• Temperatures and Precipitation, Summer 1980
• On Feb. 1, 1911, a large prairie fire destroyed farm properties and oil field equipment, including tanks filled with oil. When the flames reached the Caney River burning oil spilled onto the river causing a river of flames, which moved across the river starting a fire on the other side.
• A break in an eight-inch oil pipe dumped 1000 barrels of oil into Buck Creek, Sand Creek and the Caney River on June 18, 1980. The break began on Monday afternoon, but wasn't discovered until Tuesday morning when a drop in pressure on the line was noticed. Clean up was hampered by strong currents. Approximately 250,000 fish died due to the spill.

The Oklahoma Department of Emergency Management (ODEM) guidelines for hazard analysis provides a process for use in assessing and evaluating hazards and promotes a common base for performing the analysis by defining criteria and establishing a rating and scoring system. The table below shows the results of the hazard analysis for Washington County.
