OBJECTIVE: Evaluate feasible alternatives for the recon- 

 struction or retirement of the Milltown Dcim structure. 



DURATION ; 1984 - 1986 



CURRENT STATUS ; Originally constructed in 1907, Milltown Dam 

 is an aging structure in need of reconstruction or retire- 

 ment. During 1984, the Montana Power Company conducted 

 studies leading to engineering designs for three potential 

 alternative actions; 1) rehabilitation of the existing dam, 

 2) partial retirement, or 3) complete dam retirement. These 

 data are contained in a September, 1984 report, "Milltown 

 Hydroelectric Project Engineering Evaluation." 



Subsequent to this work, the company conducted addition- 

 al review and study at the Milltown site, leading to an 

 application to the Federal Energy Regulatory Commission, 

 "Application for Amendment of License," submitted in Septem- 

 ber, 1985. In this application, Montana Power provides 

 supporting information for reconstruction of the dam, their 

 preferred alternative.
