Limnological Sampling METHODS Assessments of water quality were started during the 2006 adult escapement and continued during open water season through the 2009 adult escapement. One primary site was sampled for dissolved oxygen, temperature, light transmission profile, Secchi disk transparency, and zooplankton densities. Samples for analysis of phosphorous, carbon, chlorophyll a, phaeophytin a, nitrogen, calcium, magnesium, iron, conductivity, pH, alkalinity, turbidity, and color were also collected with a Kemmerer sampler one meter below the surface and from the midhypolimnion. One secondary site was limited to the zooplankton density and Secchi disk transparency. Water samples were collected by CIAA and water analysis completed by ADF&G. Sample collection and analysis procedures are described by Koenings, et al. (1986). Environmental Conditions Percent cloud cover was visually estimated, stream stage was measured to the nearest tenth of a foot, precipitation measured to the nearest millimeter and water and air temperatures were recorded at 5:00 PM each day. Stream stage measurements were not comparative between seasons as staff gage location varied from year to year. Standard CIAA procedures were followed for collecting these observations (CIAA, 2006). Smolt Enumeration To enumerate the smolt migration, a smolt trap was temporarily placed in Shell Creek. The smolt trap consisted of a modified fyke net with Vexar® netting leads and a double compartment live-box. The leads and fyke net funneled migrating smolt into the live-box. A swing gate remotely controlled by the trap operators directed smolt into one of two live-box compartments where they were enumerated and a smolt sample was collected. A total count of smolt migrating from Shell Lake was made until the migration of fish exceeded 1,000 to 2,000 fish per hour. At migrations rates greater than 2,000 fish per hour, fish densities in the trap become too great and the fish become stressed. To avoid stressing the fish during periods of peak migration, a 10% sub-sampling procedure was used to enumerate the fish. 5
