     A185Produce CBFish Status ReportPeriodic Status Reports for BPAThe Contractor shall report on the status of milestones and deliverables in Pisces. Reports shall be completed either monthly or quarterly as determined by the BPA COTR. Additionally, when indicating a deliverable milestone as COMPLETE, the contractor shall provide metrics and the final location (latitude and longitude) prior to submitting the report to the BPA COTR.

     D44Enhance Nutrients in Water BodiesPurchase oxygen and inject into North Twin LakeLiquid oxygen will be purchased and delivered through OxArc. Delivery will occur every 5-14 days, on average, to a liquid oxygen tank located at the southeast corner of North Twin Lake. Via a subcontractor (Gantzer Water Resources Engineering, LLC) operated diffuser system, oxygen will be injected into the hypolimnion of North Twin Lake throughout the open-water stratification season, usually from mid-May to late-September. At total of 80,000 CCF of liquid oxygen will be delivered for injection into the hypolimnion of North Twin Lake at a rate of approximately 40 SCFM on average.Trout, Interior Redband (O. mykiss gairdnerii), Trout, Rainbow (Oncorhynchus mykiss)Bass, Largemouth (Micropterus salmoides), Trout, Brook (Salvelinus fontinalis)
     E157Collect/Generate/Validate Field and Lab DataDissolved oxygen monitoringMonitoring of hypolimnetic oxygen levels is critical to oxygenating the hypolimnion. Oxygen levels will be monitored continuously by a subcontractor (Gantzer Water Resources Engineering, LLC) with probes in fixed locations in North Twin Lake. Along with Washington State University, we will perform a monthly on-site monitoring sampling event as a quality control for the continuous monitoring probes. The data will be monitored remotely and used to control the amount of oxygen injected. Readings from oxygen sensors probes are taken every hour and recorded on a data logger. Nine oxygen sensors are located throughout the hypolimnion in North Twin Lake at the bottom (sediment water interface), and 0.5, 1.0, 1.5, 2, 3, 4, 5, and 6 meters above the lake bottom. Once a month, an oxygen profile of the lake’s water column is taken using a water quality sonde with an optical dissolved oxygen sensor at one meter intervals for data quality assurance and control. Oxygen sensor probe continuously recorded data is also reviewed for anomalies. Oxygen levels in South Twin will also be monitored to observe oxygen depletion rates for a comparison between the two systems.Trout, Interior Redband (O. mykiss gairdnerii), Trout, Rainbow (Oncorhynchus mykiss)Bass, Largemouth (Micropterus salmoides), Trout, Brook (Salvelinus fontinalis)
     F157Collect/Generate/Validate Field and Lab DataMonitor physical and biological effects of oxygenationFrom 2008 - 2016 a team of scientists from Washington State University (WSU) measured the effects of oxygenation on North Twin Lake using South Twin Lake as a reference. In 2017, data gathering will continue through a subcontract with WSU and field work performed by us as part of hatchery monitoring and evaluation. Biological and nutrient data will be gathered throughout the open-water season to coincide with the existing data set. Oxygen depletion rates in North Twin and South Twin will be monitored for a comparison between the two systems. Colville Confederated Tribes staff will collect trout condition, growth, and creel data as part of another contract.Trout, Interior Redband (O. mykiss gairdnerii), Trout, Rainbow (Oncorhynchus mykiss)Bass, Largemouth (Micropterus salmoides), Trout, Brook (Salvelinus fontinalis)
     G162Analyze/Interpret DataAnalyze and interpret dataBiological and physical parameters will be compared to historical data and between lakes to decipher the effects of hypolimnetic oxygenation. Parameters to be analyzed consist of: dissolved oxygen levels, water quality variables, zooplankton, phytoplankton, and invertebrate population dynamics, and trout condition and growth. Angler catch rates will be also be analyzed to determine if hypolimnetic oxygenation directly contributes to increased catch rates. Overall, the primary goal of the analysis is to determine the effectiveness of hypolimnetic oxygenation in North and Twin Lake using South Twin as a reference in order to guide future lake management.Trout, Interior Redband (O. mykiss gairdnerii), Trout, Rainbow (Oncorhynchus mykiss)Bass, Largemouth (Micropterus salmoides), Trout, Brook (Salvelinus fontinalis)
