Summary

This layer contains the major and supplementary lakes and reservoirs located in the US. This polygon file is intended for medium scale thematic mapping and analysis.

Description

            

The spatial data were obtained from the Natural Earth website. Major lake data originated primarily from the World Data Bank 2 with additions from other various sources, primarily imagery. Geoprocessing was performed to export US lakes and reservoirs that intersected the NE 1:10,000,000 US boundary. Supplementary lake data originated from the Commission for Environmental Cooperation (CEC). Geoprocessing was performed to export supplementary US lakes and reservoirs that intersected the NE 1:10,000,000 US boundary. The primary and supplementary exported data were merged to create a detailed layer of US lakes and reserviors. Attributes were modified to include ID, type, name, note, scalerank, dam, and year. The coordinate system of this data is WGS 1984.
