Nueces River Daily Monitoring Update – October 6–7, 2025
Tracking Changes in the Lower Nueces River and Bluntzer Groundwater Field
Daily measurements taken across the lower Nueces River system on October 6 and 7 show generally stable salinity and total dissolved solids (TDS) levels, with some variation at the well cluster site. These readings, collected using a YSI Pro30 Water Quality Meter, help track ongoing water quality conditions near the Corpus Christi groundwater projects.
Field Measurements
October 6-7th readings of the Nueces River in various locations. Instrument Used: YSI Pro30 Water Quality Meter.
October 6th, 2025 Readings
October 7th, 2025 Readings
Field Observations
The daily readings remain within normal seasonal ranges, with slightly elevated TDS values noted at the well cluster discharge point. Upstream measurements continue to show fresh to mildly brackish conditions, while downstream readings near Calallen are steady.
Well #1 remains down for repairs.
Well #4 was operating on October 6 but appears to have generator issues as of October 7.
The well cluster continues to flow, though output appears reduced compared to prior weeks.
First Look at Water Quality in Bluntzer
During the City of Corpus Christi Water Workshop held last Friday, early data from the Western Groundwater Field (Bluntzer) was presented.
According to the discussion:
Well #9 initially produced water at approximately 1,760 mg/L TDS following development.
These results represent post-development testing, meaning fine sediments (“fines”) were already flushed out and the aquifer stabilized — giving a more accurate picture of baseline long-term water quality.
The purpose of these early tests is to understand how groundwater quality stabilizes after initial pumping and what may occur during sustained high-volume use over time.
For those interested in reviewing the official public meeting:
Groundwater project discussion begins at 2:16:12
Specific Well #9 comments begin at 2:19:06
These timestamps reference the recorded Corpus Christi Water Workshop session.
Why It Matters
By pairing real-time surface water readings with updates from regional groundwater projects, residents and local organizations can gain a clearer understanding of how surface and subsurface systems interact.
Continuous monitoring not only supports transparency but also helps inform long-term decisions on how to conserve, preserve, and protect groundwater resources in Nueces County and surrounding regions.
Community Note
The Nueces Groundwater Conservation District (proposed) continues to emphasize open public data, responsible management, and scientific reporting to guide sustainable water planning.
