The Data Access System for Hydrology (DASH) is a web interface that enables you to query networks of hydrologic observation sites and extract hydrologic observation data from them in the form of time series of measurements at individual sites or collections of them. Each WATERS test bed operates a DASH, which permits access to national datasets such as the USGS NWIS network, as well as academic investigator data. Under the hood of DASH is a set of WaterOneFlow web services, which provide programmatic access to WATERS observations data. These services can be incorporated into other applications as well. Some examples are linked below.
