Scott Titzler is a scientist who supports a diversity of large river and estuarine research projects. Scott specializes in planning and designing river and estuarine instrument deployments, instrument design and testing, hardware design, and boat operations. Current and most recent work includes using acoustic telemetry to evaluate salmon and steelhead behavior and survival through the Columbia River and estuary, measuring reservoir hydraulic and thermal environments in response to hydroelectric dam operations, and the use of fixed-location hydroacoustics to evaluate fish behavior as they pass over Snake River dam surface passage routes. Additionally, he supports projects that evaluate samlonid habitat and hydrodynamic conditions near aquatic structures.
