Dos Reis, Mossdale Crossing Regional Parks Closed

San Joaquin County Park officials have announced the temporary closure of Dos Reis Regional Park as rising waters spark flood concerns at the Lathrop-area facility.

As county and state officials monitor the swift, rising San Joaquin River, growing concern over possible flooding has triggered full closure of Dos Reis, including its partially open campground.

Until now, only half of the park’s campsites were available as maintenance crews continue to deal with previous storm damage.

Mossdale Crossing Regional Park, which borders the same river, was closed by officials earlier this month due to flooding at the park’s boat launch. Both facilities join Stillman Magee Regional Park and Woodbridge Wilderness Area, which have been closed since January due to storm damage and face possible flooding from the Mokelumne River.

Park officials will continue to assess all facilities as flood concerns subside and reopen these parks once conditions improve. There is no estimated reopening date at this time.
