MonitoringLocationDescriptionText The given latitude and longitude are located in the center of Crater Lake. The site was created by NPSWRD to represent the presence/absence results collected in 1980 from the four distinct stations in the project. Authors of the source report presented some of the 1980 data in their article as species that were either present or absent from the 1980 samples without quantifying results or identifying individual stations. Authors did quantify six individual species identified by station from the July 24, 1980 samples and those results are included in the other stations' records.
