CrowdHydrology was established in 2010 with the goal of using innovative methods to collect spatially distributed hydrologic data. What began in the Northeast United States has expanded across the continent. Our hope is that we will soon be able to offer global support to those seeking to aid the study of hydrologic data worldwide.
