26.25 the river threatens the Big Bend Park employee living quarters at Rio Grande Village. Evacuations will likely be required.
25 the river continues to inundate Rio Grande Village campground. The campground store also begins to flood at stages over 25 feet (7.62 meters).
22 the river completely submerges the telemetry box near the pump house, rendering it useless.
20 the river reaches major flood stage. Rio Grande Village campground begins to flood. Evacuations may be necessary. The rain gauge near pump house will be affected.
19 the river reaches the bottom of telemetry box near the pump house.
15 the river reaches moderate flood stage. Water pumps submerge.
13 the river reaches minor flood stage. Water reaches the water pumps maintained by the park service that are used to water the campgrounds and to provide water to the employee living quarters. It may be necessary for park personnel to remove the pumps.
12 the river reaches bankfull, and no damage is expected. Preparations may be necessary to remove water pumps. The park should be notified at this time if additional rises are expected so they will have time to remove the pumps.
