We are always looking for exceptional professionals dedicated to advancing the science and practice of ecosystem restoration.
Wolf Water Resources was founded on the principles of raising the bar for ecosystem planning and design while investing in people. It is the policy of Wolf Water Resources to treat all employees, clients, vendors, and applicants for employment with dignity and respect. We provide flexibility in work schedule and telecommuting options, a generous benefits and bonus program, and ergonomic workstations for all. We provide our employees with high performance equipment and tools to do their work and support training opportunities to develop new skills. Our work is highly collaborative and creative as we develop ways to improve ecosytem designs that are supported by natural processes over time. We also look for opportunities to reduce the cost of restoration projects so that more can be done with limited funding.
Now hiring for the following positions:
Marjorie Wolfe, PE, CFM – President, Water Resource Engineer
After decades of restoring habitat in the rivers and floodplains of Oregon, Washington, and Montana, and having worked for both consultant firms and public agencies, Marjorie founded Wolf Water Resources (W2r) in 2014 to address gaps in the way restoration work was being done. Specifically, she wished to work more closely with nature by learning from each project and restoring an ecosystem’s ability to self-heal, rather than imposing engineered stability (on dynamic systems). In addition, she recognized that many restoration solutions are not entirely technical, but also require engaging with people. W2r’s founding principle of working with nature and partnering with people means recognizing the local communities that live with our projects on a daily basis, and from that, creating a project framework that reflects human needs and values.
Marjorie’s passion and dedication to her work is reflected through her involvement with professional organizations such as River Restoration Northwest, and the ASCE Environmental Water Resources Group. Her free time is spent exploring local streams and forests with her dogs.
Jeremy Lowe – Senior Geomorphologist
Jeremy translates state of the art science into a practical and implementable level on design projects, where he has built trust among many of the project stakeholders in our region. This includes a long history of working on projects in the Lower Columbia Estuary where he has helped author the USACE Shallow Water Habitat Guidelines for the Lower Columbia River and the WDFW Water Crossing Design Guidelines for Tidal Systems. Additional career highlights include designing sea defenses to reduce flooding in Venice, Italy and authoring tidal wetland guidelines for San Francisco Bay and the Puget Sound and Lower Columbia River Estuary. Jeremy also works at the San Francisco Estuary Institute where he leads the Institute’s initiatives related to rising ocean levels due to climate change.
Darlene Siegel – Aquatic Fisheries Biologist
Darlene is a senior member of our team, bringing a broad range of industry experience leading complex, multiple-objective projects from feasibility through design. She has worked in estuarine, riverine, and wetland ecosystems, analyzing limiting factors, designing and conducting habitat assessment and valuation models, and developing biological design criteria to maximize ecological uplift. She has built a strong reputation with her clients for her thorough knowledge of regulatory requirements and effectiveness at communicating with resource agencies. Darlene’s permitting experience includes environmental documentation for USACE Section 408, ESA, CWA, and NEPA.
Curtis Loeb, PE – Senior Water Resources Engineer
Over the past 20 years, Curtis has practiced water resources engineering in watersheds across the country, with a focus on surface water systems in Washington, Oregon, and California. He has guided these projects from start to finish: from technical engineering analyses and planning, to design and permitting, and construction phases.
Curtis’ experience involves preparation of detailed designs, technical specifications, cost estimates, and construction plans and schedules. He has also conducted hydrologic, hydraulic, geomorphic, and sediment transport and water quality analyses to support restoration projects. Recently, he completed final designs and provided engineering support during construction of several large tidal wetland and floodplain habitat restoration projects along streams, rivers, and estuaries in the Pacific Northwest.
Colin Thorne, PhD – Senior River Scientist
Colin brings several decades of distinguished experience in fluvial geomorphology and flood risk management in the USA, UK, and many other countries spread across five continents. As a research affiliate of W2r Colin seamlessly unites technical and stakeholder aspects of restoration projects. His work ranges from the North Fork Toutle River where he assessed the effect of grade building engineered log jams overwhelmed by sediment load from the 1980 eruption of Mt. St. Helens to the Mekong estuary where he reviewed potential impacts on sediments, morphology and nutrient balance of proposed Chinese dams.
Amanda Jones, PE, ESCM – Water Resources Engineer
Dedicated to a career in water resources restoration, Amanda’s professional experience includes fluvial and tidal channel design, fish passage enhancement, culvert replacement, floodplain and stream restoration, stormwater management, and bank stabilization. She oversees the development of our project designs, construction documents, specifications, and cost estimates. As an ODOT-Certified Erosion and Sediment Control Manager (ESCM), Amanda has created many erosion and sediment control plans and 1200C permits.
Rowyn Cooper-Caroselli, EIT – Water Resources Engineering Tech
Rowyn is a project engineer specializing in water quality and stream restoration design. His recent work as a watershed steward involved stream and water quality assessments, analysis, and report writing. He is trained as a Wilderness First Responder as well as in front country C.P.R./First Aid. His modeling capabilities include HEC-RAS, StormCAD, and EPAnet and he uses ArcGIS for data analysis and mapping. Rowyn has a diverse array of stream assessment and surveying skills including pace and compass, hand and auto level, total station, RTK, handheld GPS, laser range finding, discharge measurement, macro-invertebrate sampling, and particle counts. As an enthusiastic outdoorsman with a passion for rafting and kayaking he has developed an intimate understanding of river dynamics which he couples with his physical assessment skills to inform W2r projects.
Diedra Case, LEED AP – Business Director
Diedra brings 14 years of experience in the Architecture and Engineering industry and public relations. While practicing landscape architecture, she managed domestic and internationally-located projects and performed a variety of business development activities including producing proposals, scopes of work, and participating in project presentations. She also served actively in several professional organizations to help local development projects happen more sustainably and to organize other community AE professionals toward improving public infrastructure. Transferring this set of experiences to her work as a communications professional, she planned events and managed media strategies throughout the United States for clients in the education and technology industries; and after returning to the A&E industry she has focused on business operations and management. She enjoys working with A&E professionals and integrating her passions for visual communication and information systems to create high quality project deliverables and efficient project processes.
