Stay Weather‑Aware

We are expecting heavy rains and thunderstorms this week and are currently under a flood watch. Heavy rains in short time spans may result in high water on roads and temporary closures at low water crossings. Before heading out, residents are encouraged to check SARiverFlood.org or their local county flood website for real‑time roadway conditions: 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.

Museum Reach & San Pedro Creek

Due to the forecasted rain event, water features at San Pedro Creek and Museum Reach will be temporarily shut down to prevent failure. Service will resume once the event has passed.

Espada Park

The restrooms at Espada park are closed due to a water leak. We apologize for the inconvenience.

SASPAMCO Paddling Trail Temporarily Closed

Staff have removed two large log jams just downstream of Helton Nature Park, keeping the southern portion of the SASPAMCO Paddling Trail temporarily closed. Staff are working to contact adjacent landowners to support a land-based removal solution.
