INTRODUCTION 



The Montana Rivers Study data base represents the compilation of 

 several complex data bases from throughout the state of Montana into one 

 large data base management system. Information pertaining to Fisheries, 

 Wildlife, Recreation, Natural features, and Cultural features along 

 Montana's waterways is readily available to you through this information 

 management system. 



The master data base is maintained through the Montana Natural 

 Resource Information System in Helena, Montana. Updates to the information 

 contained in the master data base will be periodically distributed to 

 users on flexible disks as additional information is gathered and 

 collated into the master data base. 



This information management system is written in dBASE III Plus, a 

 powerful data base management software system developed and marketed by 

 Ashton-Tate. Software query, editing, listing and update programs for the 

 NRIMS system were written by William G. Enright, P.E. of Morrison-Maierle, 

 Inc., Billings, Montana. 



Users are asked to supply written comments and suggestions on how to 

 improve this system either to Larry Thompson, Program Director, Natural 

 Resource Information System, Montana State Library, 1515 E 6th Avenue,
