The impact of this biofouling pest on the economy and ecological processes in the U.S. and Canada has required prompt action on a large scale to prevent further infestations and minimize ecological degradation. This map layer is a compilation of reports of confirmed zebra mussel sightings in the United States from 1988 to January 2008. It provides geographical and historical information to show distribution over time. The reports came from a variety of Federal, State, and municipal agencies, public utilities, universities, engineering and private consultant firms. The locations of confirmed sightings were registered at 1:100,000-scale on EPA Reach File Version 3.0 and are maintained as an ArcInfo export file. This is a revised version of the May 2003 map layer Purpose: The data are an essential part of the Department of the Interior's Nonindigenous Aquatic Species Program, http://nas.er.usgs.gov/. The data were compiled for use by resource managers to make them aware of zebra mussel occurrences so that they may help to control or prevent the spread of zebra mussels. These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey or the National Atlas of the United States in the use of these data.

Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: 99%, 1% Error Attribute_Accuracy_Explanation: A zebra mussel location was included in the data base if it was confirmed by a trained biologist or by someone who had received training to be able to identify zebra mussels. Logical_Consistency_Report: No tests for logical consistency have been performed on this map layer. Completeness_Report: This data base is by no means an all inclusive listing of zebra mussel locations. But it is a fair and accurate representation of their distribution in North America. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Zebra mussel sightings were reported with varying levels of accuracy. Some of the reports were as latitude-longitude coordinates, some as river miles, and others as just a lake, beach, harbor, or a water body and nearest town name. The locations were digitized as a single point in the reported water body at the place nearest to the town. If no specific location was reported in a lake, the point was digitized in the middle. These were all small lakes; the Great Lakes had specific locations associated with them. Each zebra mussel sighting location was checked by manual comparison of the on-screen point with hard copy maps.

sighting, the location was found on a paper map. The scale of that map varied; we used the finest resolution available. The point was then digitized on- screen using ArcInfo's arcedit feature, and was referenced to EPA Reach File Version 3.0 1:100,000-scale data (ArcInfo coverages in Albers Equal Area Projection).
