Macroinvertebrate Data

Macroinvertebrate Database Browser

division bar
This Macroinvertebrate Database Browser provides the most complete access to raw data using the widest variety of query parameters.

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

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

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. Please enter a UTM range for the pool(s) selected.
