Water Quality Database Download Tool

division bar
The Water Quality Database Download Tool provides the most complete access to raw data using the widest variety of query parameters.

Please read the UMESC LTRMP Database Browser Notes before using this browser.

For Water Quality metadata read the FGDC NBII, Water Quality Metadata page.

For water component information, read the Component Information Page that contains a description, history, and value ranges of the data.

Please be aware that the quality assurrance flags are downloaded with Water Quality parameters to allow users to remove questionable data. A description of the quality assurrance flags and their use can be found in the document: LTRMP WQ QA Flag Primer. .

Queries made using the Water Quality Database Browser are real time, it may take a few minutes to retrieve your results.

The Universal Transverse Mercator (UTM) coordinates are a global grid system similar to latitude and longitude. Rather than using hemispheres, UTM coordinates divide the Earth into 60 north-south zones of 6 degrees longitude each. The UTM coordinates are the distance in meters from the central meridian (Easting) and from the Earth's equator (Northing) for each of these 6 degree zones. A zone's central meridian is the line of longitude from the 6 degree intersection with the equator to the North Pole. The UTM coordinates for all river pools are based from zone 15. Enter a UTM range for the pool(s) selected.

Another method of locating where the data were collected is by location code which is not as accurate as the UTM coordinates. The format of a location code is where r designates the river or tributary (Water quality river name abbreviations), mmm.m is the river mile (recorded to the nearest 0.1 mile), and a is an alphabetic code for the relative lateral position across the floodplain (going west to east). The default is "All Location Codes".
