CREDA; p4, '15. On' page 13, you indicate that the effects of varied flow rates from Crystal
Dam have not been quantified. What studies have been identified as necessary to determine
tbe impacts of changing to varied flow rates from Crystal Dam on downstream resources?
What is the status of those studies?

CREDA; p5, '15. On page 2 of the proposed contract it states that Reclamation and the Park
Service have determined that water released from the Aspinall Unit for CRSP project purposes
can also be utilized to meet the objectives of the Black Canyon of the Gunnison NationC1\
Monument and that the functions and purposes of both the Aspinall Unit and Monument can be
protected. What study or studies have been done to analyze these issues and provide support
