STREAM_ID:  A unique numeric identifier for each stream segment.  Stream  
            segments were aggregated from the digitized features of the  
            original source data layer.  Stream features were aggregated  
            according to Strahler stream order and connectivity.  Initially,  
            all stream features that had the same stream order and were  
            connected in an upstream-downstream relationship were aggregated  
            using an ArcInfo dissolve process.  Stream segements longer than  
            10,000 meters were then manually split at DNR minor watershed  
            boundaries. 
 
SINUOSITY:  A measure of the channel sinuosity.  This is defined as the actual  
            stream length divided by the straight line distance from one end of  
            the segment to the other end.  
 
VERT_DENS:  The vertex density for each segment expressed as the number of  
            vertices per kilometer.  
 
GEOM_SCORE: A relative rank of the natural character of the stream geometry.  
            The value is a 1, 2, or 3, with a value of three being the most  
            natural geometry.  
 
RIP_VEG:    The fraction of the land area within 60 meters of the stream that  
            is covered by natural vegetation.  Values are expressed as real  
            numbers. 
 
RIP_SCORE:  A relative rank based on the amount of natural vegetation in the  
            riparian zone based on the Rip_veg field.  The value is a 1, 2, or  
            3, with a value of three being the best natural vegetation cover.  
 
PHYS_SCORE: A relative rank of the physical condition of the stream for  
            ecological habitat.  The value is a 1, 2, or 3, with a value of  
            three being the best habitat condition.  
 
BIO_DIV:    Indicates whether a stream feature intersects a site of high  
            biodiversity as identified in the Minnesota County Biological  
            Survey (MCBS).  Values are Y or N. 
 
TROUT:      Indicates whether any portion of a stream segment is a DNR  
            designated trout stream.  Values are Y or N. 
 
NONMOBL_RE: The number of observations within the past 25 years, of rare,  
            endangered, threatened or unusual aquatic species (heretofore  
            referred to as R&E species) that are not mobile outside of an  
            aquatic environment (e.g. fish, mollusks, etc.) associated with a  
            stream segment.  
 
MBL_RE:     The number of observations within the past 25 years, of R&E species  
            that are mobile outside of an aquatic environment (e.g. reptiles,  
            birds, etc.) associated with stream segment feature.  
 
BIO_SCORE:  A relative score summarizing the known biologically significant  
            sites based on the Bio_div, Trout, Nonmbl_re, and Mble_re fields.  
            The value is a 1, 2, or 3, with a value of three having the highest  
            probability of important biological features.  
 
ECO_SCORE:  A relative rank of the overall ecological condition of the stream  
            segment based on the physical habitat condition and the known  
            probability of significant biological features.  The value is a 1,  
            2, or 3, with a value of three being the best overall ecological  
            condition.  
 
ADJ_PARK:   Indicates whether or not there is a public park adjacent to a  
            water feature.  Data for park locations was extracted from the  
            Metropolitan Council's 2000 land use dataset.  Values are Y or N. 
 
CANOE_RT:   Indicates whether a stream segment is a State designated canoe  
            route.  Values are Y ro N. 
 
FLOW_SCORE: A categorical flow rank (3, 2, or 1) based on the estimated median  
            summer flow.  Median summer flow is taken as an indicator of the  
            ability of a stream or river to support contact recreation.  A  
            higher score indicates a higher relative rank by median summer  
            flow. 
 
REC_SCORE:  A relative score summarizing the regional recreational significance  
            based on the Flow_score and Adj_park fields.  The value is a 1, 2,  
            or 3, with a value of three being more regionally important for  
            recreational use.
