Abstract:                                                                       

This coverage is a record of subbasins (4th field hucs) in Montana where native Cutthroat are known 
to be currently distributed or have been historically distributed.  This information was developed 
by fisheries personnel at MFWP (Montana Fish Wildlife and Parks) from Current distribution data and 
historical records and compiled into this GIS coverage by StreamNet staff:

Steve Carson, MFWP (stcarson@st.mt.us)
Regional StreamNet GIS Specialist, PSMFC (StreamNetGIS@psmfc.org)

Purpose:
                                                                        
Data is intended for use in a variety of applications where historic fish distribution
is important.                                        
                                                                                
Limitations_of_Data:                                                            

Data is historical in nature and thus cannot be currently verified in the field but is
instead based on the expertise of local fisheries biologists.  Distribution is resolved
only to the 4th field huc (subbasin) level where distribution shown in a 4th field huc
indicates that Cutthroat were distributed historically within at least part of this area 
but not necessarily over this entire area.

Data was collected by huc from various sources (see abstract) and then matched with a hydrologic coverage of hucs to
create a GIS coverage.
