BLM Announces Wet Weather Closures for Cow Mountain

With the coming of the rainy season, the Bureau of Land Management, Ukiah Field Office has announced that intermittent closures of the South Cow Mountain Off-Highway Vehicle Area will go into effect beginning Monday, Nov. 23.

As has been done in previous years, once the area has received an accumulation of four inches of rain, any additional rainfall amounting to a half-inch in a 24-hour period, or 1 inch in 72 hours, will result in a temporary closure to all motorized vehicles.  Non-motorized activities will still be permitted.  The area will remain closed for a minimum of three days after no measurable rain is recorded, after which a thorough inspection of the roads and trails performed by qualified personnel will determine if the area will reopen.

"The primary reason for these closures is to protect the area's resources,” said Ukiah Field Office Manager Rich Burns.  "Once they are saturated, the clay soils in the Cow Mountain area are very slippery and very soft.  The roads and trails can be severely damaged by vehicle traffic when they are in this condition."

The wet weather closure policy will remain in effect throughout the fall, winter, and spring rainy seasons. If you are planning a visit to South Cow Mountain during this time, please call the Ukiah Field office at (707) 468-4000 for closure information prior to your visit. This information is available 24 hours a day.

For more information on the South Cow Mountain wet weather closure policy, go to or contact Larry Ames, Park Ranger at (707) 468-4093.
