2 to 5 Inch Rainfall Triggers Major River Surge Across South Texas Including Atascosa, Frio and Nueces Rivers Heading Toward Lake Corpus Christi
SOUTH TEXAS — A beneficial push of water is moving down the Atascosa River into the Frio and Nueces river systems following the recent heavy rainfall event that dropped 2 to 5 inches across South Texas. Current river flow data is showing dramatically above normal readings at key gauges along the Atascosa corridor, with the surge of water heading downstream toward Lake Corpus Christi.
Atascosa River Running Dramatically Above Normal at Whitsett and Three Rivers
The most striking above normal river flow readings are located along the Atascosa River, where Whitsett is recording a remarkable 2,410 cubic feet per second and Three Rivers is showing 1,050 cubic feet per second, both marked as well above normal on current flow monitoring. These elevated readings confirm that the bulk of the recent 2 to 5 inch rainfall has been channeling efficiently through the Atascosa watershed and pushing a meaningful volume of water downstream toward the Nueces River and ultimately Lake Corpus Christi.
The contrast between the above normal blue indicators at Whitsett and Three Rivers versus the orange below normal readings at upstream locations like Derby, Cotulla, and Tilden illustrates how the rainfall was concentrated and how the flow surge is progressing through the river system.
Frio and Nueces Rivers Show Mixed Readings With Some Normal Flow Returning
Along the Frio River corridor, Laguna is showing 133 cubic feet per second and Concan is recording 38.5 CFS, with both gauges reflecting the influence of recent rainfall pushing through the system. Barksdale on the Nueces River is recording 84.5 CFS at normal levels, while Leakey on the Frio is showing normal flow conditions as well.
The Sabinal River remains largely dry with Vanderpool recording just 0.5 CFS and Sabinal nearly at zero, indicating the recent rainfall did not significantly impact that watershed.
Water Surge Heading Toward Lake Corpus Christi Providing Meaningful Reservoir Benefit
The downstream surge moving through the Atascosa into the Nueces system is heading directly toward Lake Corpus Christi, providing a welcome and meaningful inflow to the reservoir following the recent rainfall event. Any above normal inflow into Lake Corpus Christi represents genuine water supply benefit for the region during an ongoing period of below average precipitation across South Texas.
