Even though technology has improved—like better sensors, satellites, and powerful computers—we’re still missing the bigger picture. Scientists now say it’s time to connect the dots. They propose a new, large-scale effort to monitor and model headwater streams across the country. This would help us better understand where water is, how it flows, and how it might change in the future.

By building a shared network of data and models, researchers could predict floods, droughts, and water availability with more accuracy. They could also test new ideas and improve models over time. With water supplies under pressure from climate change and growing demand, this kind of smart investment could help secure clean, reliable water for people and nature alike. The tools are ready—now we need the strategy and commitment to bring them together.
