During FY 2017 PNNL will continue to collect temperature and water surface elevation data in chum salmon spawning habitat within the Ives Island area. These data will be collected near existing monitoring locations near chum spawning habitat north of Ives Island.  During FY 2017, PNNL will establish several additional monitoring locations near chum spawning habitat at the east and west ends of Ives Island.  These additional monitoring locations will be used to determine how water level fluctuations due to Bonneville Dam operations affect water surface levels and potential chum salmon redd dewatering in the Ives Island area.  PNNL will work together with BPA to obtain the required environmental permits for these additional monitoring locations.  Temperature and water level sensors will be placed inside the piezometers to record the egg pocket temperatures and water surface elevations at the site. Data from one of the locations (T2LB) will be made available by connecting the sensors to a cellular modem at the surface using a tethered buoy that will remain floating.  The primary purpose of the monitoring effort is to provide BPA and the region with real-time data that can be used to evaluate chum salmon emergence timing and redd dewatering. Monitoring will occur from November 2016 through May 2017. The surface buoy will remain at the field site from November 2015 through August 2016. These data will allow BPA to conserve water, when appropriate, to aid other species when chum salmom embryos are no longer present within the Ives Island area. Additionally the data will allow BPA to establish the reltionship between Bonneville Dam operations and river depths near important chum salmon spawning habitat in the vicinity of Ives Island.  The data will be compiled in an annual, calendar year report and provided to BPA electronically. The annual report will provide BPA with an electronic appendix of temperature and water surface elevation data, chum salmon emergence timing estimates, and a brief summary of mean temperature differences between the river and riverbed during both the chum salmon spawning and the chum salmon incubation time periods.  Results will be shared with the region as requested by BPA, including attendance at Technical Management Team meetings if requested.
