Water Resource Engineering and Habitat Restoration

Integrated
Solutions

Your water resource challenges deserve solutions that work for both your bottom line and the ecosystem. Kleinschmidt brings hydrologists, hydraulic and civil engineers, fisheries, and terrestrial scientists to the same table, turning complex constraints into cost-effective, habitat-smart designs. From the first feasibility study through regulatory approvals and construction oversight, we keep the process seamless and the outcomes dependable.

We balance local ecology, hydraulics, and your operational goals to create environmental enhancements and conveyance structures built to last. By grounding every design in field data and advanced modeling, we deliver projects that satisfy public, private, and regulatory stakeholders, so you can move forward with confidence and measurable results.

We understand the complexities of environmental permitting and restoration, and we build those requirements into the design from the start, so you can move forward without delays or surprises.

We manage every stage of the process from initial planning through post-construction monitoring. Whether you need design implementation, procurement support, construction oversight, or long-term monitoring, we act as your strategic partner, keeping your project on track, on budget, and aligned with your goals.

Our multidisciplinary approach focuses on practical, durable solutions tailored to the unique needs of each site. By streamlining restoration efforts with an eye toward regulatory approval and long-term success, we help you achieve lasting results for the environment—and for your bottom line.

Over the past decade, we’ve led 17 dam-decommissioning programs—including six under FERC jurisdiction—spanning 35 structures. Our record features six full removals, 16 feasibility studies, 11 engineering designs, and construction support on four projects, plus more than 30 dam removals across nine U.S. states and one Canadian province for private owners, utilities, NGOs, and public agencies.

You get a single, coordinated team that blends civil, geotechnical, and structural engineering with nationally recognized expertise in fish migration, aquatic habitat, and fluvial geomorphology, backed by permitting pros who navigate NEPA, FERC, and state approvals while keeping stakeholders on board. The result: cost-sensitive, ecologically sound designs that clear regulatory hurdles the first time, so you can retire outdated dams or restore fish passage quickly, safely, and with measurable benefits for your organization and the river you steward.

We design bridges and culverts that do more than meet hydraulic standards—they protect communities from flooding, support aquatic ecosystems, and stand the test of time. Our hydraulic engineers apply decades of experience using Federal Highway and State DOT standards to create designs that manage flood risk, reduce erosion and scour, and allow for the natural movement of fish and other aquatic species. We blend advanced modeling technologies—including 1D and 2D simulations—with deep expertise in fish passage and stream restoration to deliver structures that work with the river, not against it.

From flood prediction to habitat enhancement, our interdisciplinary team brings precision, innovation, and environmental awareness to every project. We collaborate with leading researchers and stay ahead of industry advancements to ensure our clients benefit from the most practical solutions. Whether designing new infrastructure or upgrading existing assets, we help you meet regulatory requirements, improve ecological connectivity, and minimize long-term maintenance, so you can build with confidence and purpose.

Since 1992, our team has delivered hydrologic and fluvial geomorphologic analyses that inform reliable, forward-thinking solutions for flood management, dam operations, habitat restoration, and infrastructure design. We use advanced modeling tools—including custom-built software and commercial platforms—to analyze everything from rainfall runoff and snowmelt to flow duration, groundwater-stream interactions, and floodplain inundation. Our GIS-based catchment assessments and flow routing analyses give clients a clear, science-backed understanding of water behavior, helping reduce risk, support compliance, and guide sound decision-making.

What sets us apart is our focus on ecology and restoration. We’ve developed hydrologic models that directly tie operational decisions to fish mortality and passage, such as a predictive tool we built for Portland General Electric to model flow changes across a three-dam system. Our engineers and internationally recognized sediment transport experts bring decades of experience in stream restoration and natural channel design, specializing in high-energy rivers and sediment-imbalanced systems. Whether restoring habitat, optimizing dam operations, or designing for resilience, our integrated approach ensures your project is grounded in science and built for long-term success.

As ecosystems face mounting pressure from urbanization and climate change, municipalities increasingly turn to sustainable stormwater strategies to restore balance. We help clients design and implement Green Stormwater Infrastructure (GSI) that manages runoff at its source—capturing, infiltrating, and reusing water through natural processes like vegetative uptake and evapotranspiration. These solutions reduce the need for costly end-of-pipe treatment systems, offering smarter, more resilient alternatives that align with local stormwater management plans.

Our approach is rooted in enhancing watershed health while delivering real-world value. By integrating innovative GSI techniques into your infrastructure, we help you reduce flooding, improve water quality, and increase community resilience while supporting economic development and environmental stewardship. Whether you’re retrofitting existing systems or developing a new stormwater strategy, we bring the expertise to make your plan sustainable, scalable, and prosperous.
