Sort	Type	Title	Start	End	Status	Modified Date
A		Environmental compliance requirements complete	3/1/2006	3/1/2006	Concluded	2/7/2006 7:02:57 AM
		Description: On-the-ground work associated with this work element cannot proceed until this milestone is complete. Milestone is complete when final documentation is received from BPA environmental compliance staff (completion can be based on pre-existing environmental documentation from BPA).
B		Install smolt traps	3/1/2006	3/15/2006	Concluded	2/7/2006 7:02:57 AM
		Description: Install traps at Lake Wenatchee and Lower Wenatchee locations.
C		Smolt trapping	3/1/2006	8/31/2006	Concluded	2/7/2006 7:02:57 AM
		Description: Operate traps on a daily basis as conditions permit. Fish will be removed from the trap at a minimum every morning and placed in an anesthetic solution of MS-222. Fish will be identified to species and counted. Non-target species will be allowed to fully recover in fresh water prior to being released in an area of calm water downstream from the smolt trap. Target species will be held in separate live boxes for use during mark/recapture efficiency trials conducted in the evening.
D		Efficiency Trials	3/1/2006	8/31/2006	Concluded	2/7/2006 7:02:57 AM
		Description: Mark/recapture efficiency trials will be conducted throughout the trapping season. The frequency of mark/recapture trials is dependent on the number of fish captured (no less than 100) and the river discharge. These trials will be conducted over the widest range of discharge possible (interval depends on trap location). Fish for the mark/recapture trials will be marked by clipping the tip of either the upper or lower lobe of the caudal fin. Fish will be placed in a live pen to recover for at least 8 h before being transported to the release site at least 1 km upstream of the trap. Marked fish will be distributed across the width of the river and along approximately 100 m of the bank in pools or in calm pockets of water around boulders. In the case of the upper Wenatchee River trap, marked fish will be transported and released into Lake Wenatchee. Fish will be released between 1800 h and 2000 h. All recaptures of marked fish typically occur within 48 h after each trial.
E		Calculate smolt production estimate	9/1/2006	2/1/2007	Concluded	2/7/2006 7:02:57 AM
		Description: Calculate smolt production estimates using appropriate methodologies. The number fish that could be marked and released may limit the frequency with which trap efficiency trials will be conducted. Emigration estimates will be calculated using estimated daily trap efficiency derived from the regression formula using trap efficiency (dependent variable) and discharge (independent variable). Trap efficiency will be calculated using the following formula:Trap efficiency, Ei=Ri/MI, where Ei is the trap efficiency during time period i; Mi is the number of marked fish released during time period i; and Ri is the number of marked fish recaptured during time period i. The number of fish captured will be expanded by the estimated daily trap efficiency (e) to estimate the daily number of fish migrating past the trap (Ni) using the following formula:Estimated daily migration = where Ni is the estimated number of fish passing the trap during time period i; Ci is the number of unmarked fish captured during time period i; and ei is the estimated trap efficiency for time period i based on the regression equation.
