These sites provide up‑to‑date information from flood‑monitoring sensors across the region. Real‑time updates are available 24/7 to help you stay informed as conditions change.

Please use caution when traveling and plan routes accordingly.

The east bank trail along San Pedro Creek will be temporarily closed between the upper trail at Cameron St. and the lower trail at two access points.

  • Once work at this location is complete and the trail reopens, construction will shift to the second closure area between the upper and lower trails on the opposite side of the green space.

Please follow posted signage and plan alternate routes. We appreciate your patience as this work is completed.
