Water Quality Database

Click here to go directly to the Water Quality Database, Interactive Map, and Data Entry.

All data collected through the IDAH2O program are submitted to a publicly-accessible database by using a set of online forms. These forms are are actually a web application that is connected to the University of Idaho's Northwest Knowledge Network (NKN), in partnership with IDAH2O. NKN is a secure central data storage system that allows easy access and processing of data from anywhere. This database is a part of a larger Hydrologic Information System (HIS), called CUASI, for sharing water data. 

As a system, this HIS operates similarly to the way in which most people browse the internet. There is a server that hosts data, a central catalog that mines data and enables discovery (like a search engine such as Google), and a client that allows you to browse data (like a web browser such as Internet Explorer or Google Chrome). 

Data submitted by volunteers is posted and available almost immediately. Individual reports for sites or specific water quality parameters can be generated with the IDAH2O web application, or by contacting the IDAH2O program coordinator. Volunteers or distant users can create graphs and charts, and can look at data collected at any IDAH2O registered site for which data exists. Each volunteer has a unique password, used to upload data. Contact us if you have questions about the data, data entry, changing passwords, or the larger Hydrologic Information System components.
