DEPARTMENT OF THE INTERIOR

Bureau of Reclamation


Arrowrock Dam Outlet Works Rehabilitation

AGENCY: Bureau of Reclamation, Interior.

ACTION: Notice of Availability of Record of Decision.

-----------------------------------------------------------------------

SUMMARY: This notice is issued under authority of the National 
Environmental Policy Act of 1969. The Record of Decision (ROD) signed 
on April 30, 2001 contains the decision of the Department of the 
Interior, Bureau of Reclamation (Reclamation) Pacific Northwest Region, 
to select and implement the Preferred Alternative (Alternative A), as 
described in the Final Environmental Impact Statement (FEIS). 
Alternative A was identified as the environmentally preferred 
alternative in the FEIS. This alternative best achieves the project 
objectives and meets the purpose and need of the project in an 
environmentally sensitive manner.

ADDRESSES: Copies of the ROD may be requested from the following 
locations:
     Bureau of Reclamation, Pacific Northwest Region, 1150

SUPPLEMENTARY INFORMATION: Pursuant to section 102(2)(C) of the 
National Environmental Policy Act of 1969, as amended, Reclamation 
prepared a FEIS to examine the impacts of alternative methods to 
rehabilitate the outlet works at Arrowrock Dam by removing the 10 lower 
level Ensign valves and replacing them with clamshell gates. Two action 
alternatives were identified that differed only in the timing of 
reservoir drawdown and the elevation of Arrowrock Reservoir and Lucky 
Peak Lake in the third construction season. The preferred alternative 
(alternative A) requires a longer period of drawdown of Arrowrock 
Reservoir, but both Arrowrock Reservoir and Lucky Peak Lake would 
remain at a higher elevation than with the other action alternative. 
Based on comments received on the Draft EIS concerning impacts to water 
quality and bull trout, the preferred alternative was modified so that 
the probability of sluice gate use, which could release large amounts 
of sediment form Arrowrock Reservoir, was reduced from 42% to 15%. The 
No Action Alternative, which included actions that would be required 
for an intensive maintenance program if the Ensign valves were not 
replaced, was also evaluated.

    Dated: May 24, 2001.

Acting Regional Director.
