Integrated Status and Effectiveness Monitoring Program (ISEMP)

ISEMP was a large-scale collaborative program implemented by agencies and contractors throughout the Columbia River basin, guided by several objectives related to management and recovery of ESA-listed salmon and steelhead populations as detailed in the 2008 Federal Columbia River Power System Biological Opinion (FCRPS BiOp).  The objectives were to 1) design, evaluate and implement status and trends monitoring of fish and their tributary habitats, and 2) monitor watershed scale effectiveness of management and restoration actions impacting these fish and habitats.  During the 13-year history of the program, ISEMP informed the design and prioritization of habitat restoration and enhancement projects, as well as the development of monitoring efforts by providing regional salmon management agencies with data, information and analysis tools.  For more than a decade, Terraqua was responsible for coordinating and implementing ISEMP in the Upper Columbia region of Washington State, and working with collaborators in the John Day watershed (OR), and South Fork Salmon River and Lemhi River watersheds (ID).  In addition to program coordination, study design development and integrated annual report writing, Terraqua was responsible for generating, curating and analyzing large datasets, which have provided fundamental pieces to the Upper Columbia region's fish population recovery prioritization framework.  

 

Columbia Habitat Monitoring Program (CHaMP)

BPA began development of the CHaMP program in 2011 to further build upon ISEMP efforts to understand fish-habitat relationships and evaluate the effectiveness of fish habitat restoration and enhancement projects, as well as provide detailed insights into the status and trends of tributary fish habitat throughout the interior Columbia River basin, as required by the 2008 FCRPS BiOp.  The CHaMP protocol is one of the most technologically advanced habitat monitoring protocols available, because it includes a high resolution topographic survey and derivate models that leverage the digital elevation model that is created from the survey.  Terraqua staff worked as program coordinators with a leading role in budgeting, implementation, protocol development, programmatic protocol training and data collection.  Terraqua collected CHaMP data at more than 800 visits to over 300 unique sites spread across the upper and interior Columbia River Basin, and used this data to inform large network-scale and reach-scale datasets and models, including hydraulic models, habitat suitability indices, carrying capacity estimation, bioenergetic models and stream network analyses.

 - Battle Creek Watershed Conservancy - 

Terraqua has worked for many years on a variety of projects representing BCWC in policy arenas pertaining to the management of Coleman National Fish Hatchery and the land and waters of Battle Creek, California. Most recently, Terraqua was hired to conduct an assessment of the sediment sources and factors responsible for erosion in the Battle Creek watershed. The motivation for the assessment was to better understand the causes of a  recent increase in erosion, which cause damage to downstream infrastructure as well as degraded habitat occupied by ESA-listed fish populations.  To better understand how a recent wildfire, salvage logging, and intense precipitation and runoff contributed to this increase in erosion, Terraqua used a combination of remote sensing methods, including photogrammetry, and an analysis of radionuclides in soil samples to quantify rates of sediment production and delivery across the watershed.  Regional and state agencies are using the results from the assessment as the basis for a management plan to prescribe landscape rehabilitation projects.
