I am a fish biologist with the WFRC Columbia River Research Laboratory. I joined the USGS in 2000, and my research has focused on Pacific salmon and dams in the Pacific Northwest. My expertise includes the use of imaging sonar systems to monitor abundances and behaviors of fish near collection and passage sites, as well as passage, migration, and survival of salmonids using acoustic telemetry.
Research Interests:
My research interests include the evaluation of dam passage and survival, development of fish passage options at high-head dams, reintroduction of salmon and steelhead to areas blocked by dams, and predation and behavioral studies near entrances to fish collection structures. I am currently working on studies that evaluate the effects of tidal cycles on juvenile salmon and native fish survival, assessments of migration and survival of juvenile salmon, and developing methods to automate imaging sonar data processing.

Habitat-specific foraging by striped bass (Morone saxatilis) in the San Francisco Estuary, California: Implications for tidal restoration
Non-native predatory fish strongly impact aquatic communities, and their impacts can be exacerbated by anthropogenic habitat alterations. Loss of natural habitat and restoration actions reversing habitat loss can modify relationships between non-native predators and prey. Predicting how these relationships will change is often difficult because insufficient information exists on the habitat-specif

Evaluation of fish behavior at the entrances to a Selective Water Withdrawal structure in Lake Billy Chinook, Oregon, 2021
Imaging sonar was used to assess the behavior, abundance, and timing of fish at the entrances to the Selective Water Withdrawal (SWW) intake structure located in the forebay of Round Butte Dam, Oregon during the spring of 2021. The purposes of the SWW are (1) to direct surface currents in the forebay to attract and collect downriver migrating juvenile salmonid smolts (Chinook salmon [Oncorhynchus

Potential effects of sea level rise on nearshore habitat availability for surf smelt (Hypomesus pretiosus) and eelgrass (Zostera marina), Puget Sound, Washington
In this study we examine the potential effects of three predicted sea level rise (SLR) scenarios on the nearshore eelgrass (Zostera marina L.) and surf smelt (Hypomesus pretiosus) spawning habitats along a beach on Bainbridge Island, Washington. Baseline bathymetric, geomorphological, and biological surveys were conducted to determine the existing conditions at the study site. The results of these

Monitoring fish abundance and behavior, using multi-beam acoustic imaging sonar, at a Selective Water Withdrawal structure in Lake Billy Chinook, Deschutes River, Oregon, 2020
Collection of juvenile salmonids at Round Butte Dam is a critical part of the effort to enhance populations of anadromous fish species in the upper Deschutes River because fish that are not collected at the dam may either incur increased mortality during dam passage or remain landlocked and lost to the anadromous fish population. Adaptive resolution imaging sonar systems were used to assess the be

Monitoring native, resident nonsalmonids for the incidence of gas bubble trauma downstream of Snake and Columbia River Dams, 2021
In 2020, a new spill program was implemented to aid the downstream passage of juvenile
salmonids at mainstem dams on the Snake and Columbia rivers. Under this program, the total
dissolved gas (TDG) cap was increased to 125% and monitoring of native, resident nonsalmonid
(NRN) fishes for gas bubble trauma (GBT) became a requirement. The primary objective of this
work was to measure the incidenc

Predator and prey events at the entrance of a surface‐oriented fish collector at North Fork Dam, Oregon
Quantifiable estimates of predator–prey interactions and relationships in aquatic habitats are difficult to obtain and rare, especially when individuals cannot be readily observed. To overcome this observational impediment, imaging sonar was used to assess the cooccurrence of predator‐size fish and juvenile salmonids, Oncorhynchus spp., at the entrance to a floating surface collector (FSC) in the

Evaluation of the hydraulic and biological performance of the portable floating fish collector at Cougar Reservoir and Dam, Oregon, 2014
The biological and hydraulic performance of a new portable floating fish collector (PFFC) located in a cul-de-sac within the forebay of Cougar Dam, Oregon, was evaluated during 2014. The purpose of the PFFC was to explore surface collection as a means to capture juvenile salmonids at one or more sites using a small, cost-effective, pilot-scale device. The PFFC used internal pumps to draw attractio

High-speed limnology: Using advanced sensors to investigate spatial variability in biogeochemistry and hydrology
Advanced sensor technology is widely used in aquatic monitoring and research. Most applications focus on temporal variability, whereas spatial variability has been challenging to document. We assess the capability of water chemistry sensors embedded in a high-speed water intake system to document spatial variability.
