stream to allow adults and ducklings to move through continous habitat during the breeding season. 

 They also are intended to maintain habitat for the harlequin duck food supply, aquatic insects, minimize 

 disturbance, and prevent increases in spring and summer flows that can negatively impact productivity 

 by washing away nests and/or ducklings. Water management guideline WM-3 is intended to prevent 

 sedimentation that can negatively affect the harlequin duck food supply and their foraging ability, and 

 to prevent disturbance of ducks during the breeding season. 



WM-1. For hydroelectric and other water development proposals, maintain instream flows and habitat 

 conditions (including connectivity to facilitate brood movements) suitable for achieving the 

 conservation strategy goal. Coordinate this process with the appropriate state agencies. 



WM-2. Hydroelectric facilities will be located, operated, and maintained to eliminate adverse effects 

 that are inconsistent with attainment of the conservation strategy goals. 



WM-3. Schedule instream projects involving excavation or other disturbances outside the harlequin 

 duck breeding season unless they can be designed to be compatible with acheiving the 

 conservation strategy goal. 



Minerals management 



Minerals management guidelines are intended to maintain the long term water quality and quantity 

 necessary for sustaining the harlequin duck food supply, aquatic insects, and the clear water necessary 

 for foraging. They are also designed to protect riparian nesting habitat and security cover, and to avoid 

 human disturbance during the breeding season. Guideline MM-3 focuses on maintaining sufficient 

 water in the stream to allow adults and ducklings to move through continous habitat during the breeding 

 season. 



MM-1 Require an approved plan of operations, reclamation plan, and reclamation bond for any 



mineral operation that could affect achievment of conservation strategy goals. Reclamation 

 plans will contain measurable attainment and bond release criteria for each reclamation 

 activity. 



MM-2 Locate structures, support facilities, and roads compatible with maintaining habitat necessary 

 to acheive conservation strategy goals. When a road is no longer required for mineral 

 activities, it will be obliterated and stabilized. 



MM-3 Maintain minimum yearound water flows in the stream channel consistent with flows occuring 

 the absence of the facility development. 



MM-4 Prohibit solid and sanitary waste facilities within riparian areas that are inconsistent with 



acheiving conservation strategy goals. If no practical alternative exists to locating mine waste 

 (waste rock, spent ore, tailings) facilities within riparian areas, and releases can be prevented 

 and stability can be ensured, then: 



a. Analyze the waste material using the best conventional sampling methods and analytical 



techniques to determine its chemical and physical stability characteristics.
