The Five Value Classes Originally Proposed 

 for the Rivers Study 



Class I. Sites listed in or determined eligible for listing in the National 

 Register of Historic Places have been recorded on the river segment. 



Class II. Sites have been recorded on the river segment and may be eligible 

 for listing in the National Register of Historic Places. 



Class III. No sites have been recorded but there is the potential for 

 National Register eligible properties on the river reach 



Class IV. No possibility of significant cultural resources existing on the 

 river segment. 



Class V. Not enough information available to classify the river segment 

 in categories I, II, III, or IV. 



If a river segment can be placed within more than one class the category of 

 highest significance (the lower numbered category) will be used for mapping 

 purposes.
