In my last post we explored a powerful truth: there is enormous untapped energy already embedded in the hydropower infrastructure we’ve built. The opportunity isn’t to start over—it’s to do more with what we already have. But that insight leads to a deeper question: If we can unlock more from our infrastructure… can we also restore more of what we’ve disrupted? The answer is yes. And it begins with taking a more natural approach.

The Problem We Built Into Our Rivers

For generations, we’ve depended on rivers for energy, water, and economic growth. Dams, culverts, and diversions have delivered enormous value—but they’ve also fragmented the very ecosystems they rely on.

Fish passage is a simple idea with profound implications: fish need to move. They migrate to feed, to avoid stress, and—most critically—to reproduce. When that movement is blocked, entire life cycles break down.

Across the United States alone, millions of barriers interrupt these natural migrations, cutting off access to habitat and contributing to population declines. We’ve spent decades trying to patch this—ladders, lifts, bypasses. Some work. Many don’t. Most are expensive, rigid, and built around the infrastructure—not around the fish.

Rethinking the Starting Point

A more natural way forward begins with a shift in perspective. Instead of asking: “How do we force fish through the system we built?” We ask: “How do we let fish behave the way they were meant to—and design around that?”

In nature, movement is continuous. Rivers are pathways, not obstacles. Energy, nutrients, and species flow freely across entire watersheds. Healthy aquatic systems depend on this connectivity—not just for fish, but for entire ecosystems, economies, and cultures tied to them. So the goal isn’t simply passage.  The goal is restoring passage continuity. From mechanical solutions to biological alignment this is where fish passage has needed to evolve.

Traditional infrastructure tries to engineer over the problem, by building bigger structures, add more concrete, and forcing compliance through flow and barriers.

  •  But nature doesn’t work that way. A more effective approach is to:
  •  
  • -Meet fish where they already are
  • -Leverage instinct, not resistance
  • -Minimize handling, delay, and stress
  •  

When fish move voluntarily—on their own timing, following natural cues, without an unnatural amount of burst swimming—the entire system performs better. We see faster passage, lower mortality, better outcomes across the entire migration cycle. That’s not just theory—it’s a design principle.

The Emerging Model: Flexible, Adaptive, Scalable

A more natural future for fish passage shares a few defining characteristics:

  1. Volitional Movement: Fish choose to enter, rather than being forced.  This aligns with instinct and reduces delay and stress.
  1. Minimal Infrastructure Impact: Solutions that work with existing dams—rather than requiring massive reconstruction—allow for faster deployment and broader adoption.
  1. Species Awareness: Different species behave differently. A one-size-fits-all system doesn’t reflect biological reality.
  1. Data-Driven Adaptation: Modern systems can now observe, identify, and adapt in real time—transforming passage from a static design into an intelligent system.

Why This Matters Now

This shift isn’t happening in a vacuum. We are entering a period where three forces are converging:

  • -Climate pressure is changing where and when fish move
  • -Aging infrastructure is due for reinvestment
  • -Clean energy expansion depends on hydropower remaining a viable contributor for the foreseeable future – at least 50 more years
  •  

Fish passage sits at the center of all three. Hydropower remains one of the most reliable renewable energy sources—but its long-term role depends on balancing performance with ecological responsibility. The good news is that this is no longer a tradeoff. A more natural approach doesn’t force us to choose between energy or ecosystems and performance or restoration, it allows us to do both—better.

A Watershed-Level Opportunity

If we step back, the opportunity becomes much larger than solving individual projects. There are over a million barriers globally that affect fish movement. We don’t need a custom megaproject for each one. No community can afford that approach, and neither can the fish.

We need solutions that are:

  1. Modular
  2. Rapid to deploy
  3. Cost-effective
  4. Scalable across entire river systems

That’s how we move from isolated wins to watershed-scale recovery.

The Path Forward

A more natural way forward is not about going backward. It’s about integrating everything we’ve learned about engineering precision, biological understanding, data intelligence, and applying it in a way that respects how rivers—and fish—actually work, in real time. Because when we align with nature instead of working against it systems become more efficient, outcomes become more predictable, solutions become more deployable, and the impact multiplies.

We’ve spent decades building systems that reshape rivers. Now we have the capability—and responsibility—to build systems that restore them. Not by removing everything we’ve built. But by making what we’ve built work with nature again, even as nature changes. That is the more natural way forward.
