Research

Risks and effectiveness of benthic barriers as tools to eradicate infestation of Asian clams in the Ellisport Bay treatment area of Lake Pend Oreille, Idaho
Hope, ID
The goal of this research is to delimit the distribution of the non-native Asian clam in Lake Pend Oreille where they were discovered in 2012, and to examine if impermeable benthic barriers can be used to eliminate the infestation.
2014-2015.

Willow Creek Reservoir Water Sampling in 2014 and determination of Internal Loading
Heppner, OR
The focus of this work is to sample bi-weekly water quality parameters throughout the growing season and examine the internal load of phosphorus that accumulates in the bottom waters from the sediments while the lake is thermally stratified. This internal loading will be tied to the whole lake nutrient budget to help understand the recurrence of toxic blooms of cyanobacteria that result in lake closures.
2014-2015

Experimental determination of the role of phosphorus on the growth of Didymosphenia geminata in the Kootenai River, Montana, downstream from Libby Dam
Libby, MT
The goal of this project is to determine potential management strategies that could be employed at the whole-river scale to reduce the occurrence of blooms of Didymo, a stalked diatom that displaces large invertebrates which serve as food for endangered fish species and trophy fisheries. We are using a mobile experimental flume facility with 32 flumes to experimentally determine the effectiveness of various treatment.
2012-2015

The juvenile steelhead food web in an effluent dominated stream, Troy, Idaho, determined using stable isotopes.
Troy, ID
The goal of this project is to understand the incorporation of nitrogen from the Troy wasterwater treatment plant in the foodweb of the West Fork of the Little Bear Creek which is one of the highest steelhead producing streams in the Potlatch River system.
2014-2015.

Completed projects

Willow Creek Reservoir Water Sampling in 2013 and characterization of inflows from subwatersheds
Heppner, OR
The goal of this research was to sample water quality parameters in Willow Creek Reservoir during the 2013 growing season and to determine the sub-catchment contribution of sediment and phosphorus.
2013-2014

An examination of the spatial and temporal distribution and density of Mysis and zooplankton and implications for the survival of kokanee fry in Lake Pend Oreille
Sandpoint, ID
The goal of this research was to identify hotspots of mysids and zooplankton in Lake Pend Oreille to inform the stocking location and timing of hatchery-reared kokanee to increase their probability of survival. We also developed a method to identify prey suitable for various sized kokanee.
2011-2014

A rearing protocol for the Illinois cave amphipod, Gammarus acherondytes, to supports its recovery.
Waterloo, IL
We reared the federally endangered Illinois cave amphipod and surrogate species in the laboratory to establish under which conditions they would flourish and to develop a rearing protocol to establish robust laboratory populations.
2009-2012

Outreach

Limnology of Fernan Lake / Adventure Learning workshop
Coeur d’Alene, ID
Led a workshop to teach middle school and high school teachers about limnology and opportunities to incorporate limnology into their curriculum
Jun 16, 2014.

Scientist in Residence, McCall Outdoor Sciences School
McCall, ID
Led approximately 65 sixth graders in exploration of lakes in winter by coring through the ice and taking water and biological samples.
Mar 18-21, 2014
