Despite frigid temperatures, the January 31 and February 3 rains have boosted streamflow in Cypress Creek and the Blanco River and … Continue reading Three-month Dry Spell Ends with Icy Precipitation
The scientific report documenting the summer 2021 well visits is now available. The Lower Trinity and Middle Trinity Aquifer potentiometric surface maps presented in this report are indices for aquifer health and characterize Trinity Aquifer flow regimes in-depth. The maps provided are compared to previous studies and will be valuable timestamps for future studies. Additionally, … Continue reading Results from Well Visits – Trinity Aquifers
Every year since 1984, volunteers with the Wimberley Water Advisory Group have sampled 10 sites on Cypress Creek and the Blanco River to monitor long-term bacteria trends. This program continues with support from the Wimberley Chamber of Commerce, the Watershed Association, the Wimberley Community Civic Club, and the Wimberley Lions Club. Special thanks to Pete … Continue reading Final 2021 Ecoli Bacteria Results for Cypress Creek and the Blanco River

After runoff subsided, springs continue well above previous baseflow conditions. Pre-rain conditions at Pleasant Valley and Park Springs on the Blanco River upstream of Fischer … Continue reading Rain brings increases in spring flow and groundwater levels
Aquatic species, like freshwater mussels, are particularly useful as indicators of water quality. They have limited range and rely heavily on the surrounding aquatic community to reproduce. Since they’re largely immobile, water quality and habitat degradation pose significant risks. Loading of creeks and rivers with fine sediments, low-flow and drought, and water quality changes negatively … Continue reading US FWS Proposed Listing for Six Texas Mussel Species
