Represents spatial predictions of biological condition at unsampled streams and lakes across the counterminous US. Also includes spatial predictions channel dimensions of unsamples streams. This dataset is not publicly accessible because: Demonstrated methodology for how they proposed to do the research. Produced prelimiary results, and used them to highlight limitations in current modeling. Data should not be accessed by the public, as it is still preliminary data. Another paper will be written at a later date that will include the final data. It can be accessed through the following means: It's not accessable at this time - preliminary data. Format: Tables with 1.1 million records for streams and 200,000 records for lakes - a combination of the StreamCat / LakeCat / NARS data that is already avaiable on epa external webpages.
