Flood Impacts & Photos Collapse

38 The base of us Highway 81 bridge is flooded.
20 Major and massive lowland flooding occurs. Evacuations of livestock and a few residential properties along the river required. Many roads near the river will flood, including FM 3408 from I-35, Valley Wells Road, the frontage road near mile marker 67. Flooding also occurs on Dobie Road including in and around Highway 624. FM 624 also floods south of Highway 97 toward Fowlerton.
18 Major widespread lowland flooding occurs, and many cattle have to be evacuated. Many roads near the river begin or are near flood, including FM 3408 from I-35, Valley Wells Road, the frontage road at mile marker 67. Flooding occurs on portions of Dobie Road including in and around Highway 624, and South of Highway 97.
17 Major lowland flooding above Cotulla to below Tilden. Irrigation equipment, oil well pump jacks and tank batteries, hunting cabins and livestock cut off in wide areas of the flood plain.
15 Moderate lowland flooding occurs. The peripheral channels between Cotulla and Tilden cut off areas of the flood plain, and isolate or drown cattle. Irrigation pumps, oil field tanks, and hunting cabins are flooded near the river.
12 Overbank conditions occur as the flow reaches low areas of the flood plain. The river overbanks the flow in marshy land downstream, and cuts off areas of the flood plain. Some livestock are potentially affected downstream.
9 The river flows over its banks in the marshy land downstream, and cuts off areas of the flood plain. Some livestock are potentially affected downstream.
