The Mt. Hood National Forest says beginning today Forest Road 1300 will be barricaded and closed at the junction with Jones Creek Road on weekends when capacity limits at Lost Lake Resort and Campground area met.  That’s four miles from the entrance to Lost Lake.  Forest officials say vehicle parking along the entrance roads to the resort has become a public health and safety concern, adding emergency personnel cannot get through when the roads become congested.  Visitors are advised to have a backup plan if forest locations are full, and do not park in the road where you could prevent someone from receiving lifesaving care from emergency response.  Forest officials advise that arriving before 9 a.m. or after 4 p.m., and visiting during the mid-week are great ways to beat the crowds.
