Nueces River Monitoring October 11, 2025
Overview
As fall settles across South Texas, the Nueces River continues to show steady flow and consistent water quality readings. Conditions have remained balanced through early October, with only slight fluctuations between upstream and Hazel Bazemore locations. These observations are part of NGCD’s ongoing effort to monitor trends in salinity, temperature, and total dissolved solids (TDS) — vital indicators of both surface water and groundwater health.
Readings
Upstream
.6 salinity
817 mg/L TDS
80.3°
Hazel Bazemore Boat Ramp
1.1 salinity
1392 mg/L TDS
80.3°
Readings remain consistent across both sampling points, with slightly elevated salinity and TDS at Hazel Bazemore compared to upstream. Temperatures continue to hold steady as seasonal conditions begin to shift.
Monitoring these measurements helps track trends in surface water quality and groundwater interaction within the Nueces River Basin.
Why These Readings Matter
Each measurement tells part of the story of the Nueces River’s relationship with the Gulf Coast Aquifer. When salinity or TDS levels rise, it can indicate reduced freshwater flow or early signs of saltwater intrusion. By maintaining consistent monitoring, NGCD helps ensure the long-term protection of rural water supplies, ecosystems, and landowners’ resources.
Steady temperatures and balanced readings like those seen this week show a healthy connection between rainfall, flow, and aquifer recharge — essential for sustaining both agricultural and municipal needs in the region.
