ARBCON Observer Locations
ARBCON Observer Locations

The ARB Cooperative Observer Network (ARBCON) is comprised of nearly 550 volunteer observers across the state of North Dakota. Since 1977, observers have recorded daily rainfall and hail occurrences at their locations for the months of April through September of each year. Starting in October 2010, some observers began snowfall reporting, thus making the network operational on a year-round basis.

ARBCON reports are all available to be viewed or downloaded through the mapping and data resources on this site.

The Interactive Precipitation Mapping link is a mapping resource for quickly displaying ARBCON data.

The Department of Water Resources Map Services are a variety of internet map servers with various themes. Our general map service uses the Department of Water Resources' vast data resources such as water data locations, drillers’ logs, aquifers, and precipitation info to integrate with spatial data holdings including aerial photography, geo-political boundaries, transportation, and hydrographic features. Our specialized map services are designed for specific data sets. We also have specialized map services related to the data they are designed to deliver such as the LiDAR map service, survey map service, and an aerial imagery map service.
