see https://waterservices.usgs.gov/rest/Site-Service.html for a complete list of options. A list (or lists) can also be supplied. One way to figure out how to construct a WQP query is to go to the "Advanced" form in the Water Quality Portal: https://www.waterqualitydata.us/#mimeType=csv&providers=NWIS&providers=STEWARDS&providers=STORET Use the form to discover what parameters are available. Once the query is set in the form, scroll down to the "Query URL". You will see the parameters after "https://www.waterqualitydata.us/#". For example, if you chose "Nutrient" in the Characteristic Group dropdown, you will see characteristicType=Nutrient in the Query URL. The corresponding argument for dataRetrieval is characteristicType = "Nutrient". dataRetrieval users do not need to include mimeType, zip, and providers is optional (these arguments are picked automatically). |
