The U.S. Geological Survey’s WaterNow service can send users up-to-date water information via text or e-mail.
Users can visit the service’s mapper and find a gauge located in their area. From there, they send that gauge’s site number to the service by text or e-mail and the service responds with up-to-date data within minutes.
