Because the
United States Forest Service has not made the Mark O. Hatfield Memorial Trail an official trail yet, and because some proponents of the trail would rather see it run past some remote landmarks such as Mt. Talapus, Eagle Butte, and Table Mountain, the exact course of the trail is still undetermined. All of these landmarks lie within the Bull Run Watershed, which is closed to the public under Public Law 95-200 (PL 95-200 or Bull Run Act). An alternate route, which avoids the Bull Run Watershed boundary, is currently used by hikers, although they do not have the opportunity to see some of the aforementioned places deep in the
Columbia River Gorge when hiking this route. Some hiking is legal in the Bull Run Watershed Management Unit, "including of the Pacific Crest Trail, of the Huckleberry Trail, and of the Oneonta Creek Trail," according to
Oregon Health Authority's report on drinking water from 2011. This includes some usage by pack animals. The Mark O. Hatfield Memorial Trail would share some of the Pacific Crest Trail through the Bull Run Watershed and use some decommissioned roads (both in and out of the watershed). As of July 16, 2012, The Bull Run Watershed Management Unit, the Forest Service, nor the
Portland Water Bureau have allowed for hikers to use any of the sections of the Bull Run Watershed, holding up an official version of the trail. On August 1, 2012, the
Oregonian newspaper reported that the
Portland Police Bureau were loaning
FLIR surveillance equipment to the
Clackamas County Sheriff's Office for the purpose of detecting people in the Bull Run Watershed.
Portland City Council would need to vote on the issue of allowing additional hiking trails to be used in the watershed, but no vote is on the docket so far. ==Trail name and signage==
