Winter Ecology in the Delta - Dissolved Oxygen

The purpose was to collect water quality, sediment quality and hydrologic data during the late-winter, low-flow period (i.e., late February to early March) to address the following questions for distributaries in Segment 1: 1. Is Biological Oxygen Demand (BOD) as measured at the Alberta Environment and Water (AEW) long-term monitoring site at Old Fort representative of BOD in distributaries of Segment 1? 2. What is the range of SOD values in Segment 1 distributaries? 3. What discharge of water exists in distributaries at the point of cut-off (i.e., level of discharge at which declining DO might negatively affect fish habitat) from inflow waters?
