Why does the District care so much about monitoring wells and pump tests? Here's the short answer: because what we don't measure, we can't manage.
Beneath our feet, water moves through rock and sediment in ways that aren't visible from the surface. Our network of monitoring wells gives us a window into that invisible world, tracking water levels through wet and dry seasons, during heavy pumping, and during recovery. Every data point tells part of the story of how our aquifer is behaving.
Pump tests take it a step further. By carefully pumping a well at a known rate and observing how nearby water levels respond, we can calculate real aquifer properties, how fast water flows through the rock, how wells influence each other, and how much the aquifer can sustainably yield. That's not guesswork. That's science.
All of that field data feeds directly into our groundwater flow model, a computer simulation of how water moves through our aquifer system. The more monitoring data and pump test results we plug in, the more accurate that model becomes. An accurate model means better decisions: smarter permitting, more reliable forecasting, and a clearer picture of long-term water availability for landowners, farmers, and families who depend on groundwater every single day.
We're committed to doing this work because the decisions we make today will shape the water supply our kids and grandkids inherit.
