Nueces River Update — October 15, 2025
Tracking Salinity and Total Dissolved Solids (TDS) Across Key Monitoring Points
Today’s Nueces River readings show notable differences between upstream, well sites, and the Hazel Bazemore boat ramp — and highlight why ongoing monitoring remains so important for water quality in coastal regions.
Measurement Summary
Upstream: 0.7 salinity | 879 mg/L TDS | 77.4°F
Well 1: 4.5 salinity | 5,298 mg/L TDS | 80.3°F
Well 4: 2.8 salinity | 3,403 mg/L TDS | 78.7°F
Hazel Bazemore Boat Ramp: 1.0 salinity | 1,315 mg/L TDS | 79.1°F
Well 1’s elevated TDS (5,298 mg/L) and salinity (4.5) levels are a reminder of how quickly conditions can fluctuate depending on rainfall, discharge rates, and ongoing maintenance. With the well cluster currently offline for maintenance, these readings provide a snapshot of active system behavior under current flow conditions.
Consistent tracking like this helps pinpoint where saltwater influence increases and where aquifer quality could be at risk — vital for both conservation planning and sustainable groundwater management.
