Recovery Team Accomplishments through August 2015

  • 232 miles (63% completion) of the damaged roads
  • 52 miles (33% completion) of the damaged trails
  • 15 facilities  (campground, day-use areas, fishing and river access sites) restored and 12 decommissioned as no reasonable options to rebuild exist
  • Repaired 1 bridge and removed two destroyed bridges, including site restoration

Safety: Remember, your safety is your responsibility. Due to the flood forest officials have closed some roads, trails, and facilities on the Boulder and Canyon Lakes Ranger Districts. Please use caution in all flood affected areas. If you encounter an unsafe situation on a road or trail that is open, please stop and turn around. Emergency response access is limited due to flood damage.

Hazard Tree Information: The flood has caused destabilization of trees due to saturated soils and erosion. Use caution, especially on windy days.
