Oregon farmer converts barley farm into wetland refuge for endangered fish

Oregon farmer converts barley farm into wetland refuge for endangered fish

Built World

70-acre project near Klamath Falls draws 140 bird species and raises rare suckers

Yesterday: Story goes viral on Reddit

Overview

Updated 1 hour ago

In 2021, Karl Wenner, a co-owner of Lakeside Farms near Klamath Falls, Oregon, bulldozed 70 of his 400 acres of barley fields into a wetland. Four years later it hosts at least 140 bird species and has successfully raised federally endangered suckers to adulthood.

The project was built to solve a phosphorus pollution problem: the farm's spring-fed runoff was exceeding state limits for Upper Klamath Lake. Instead of treating the water, he turned it into habitat. The wetland now acts as a natural filter, soaking up nutrients while providing sanctuary for migrating waterfowl and rearing ground for c'waam and koptu, two sucker species sacred to the Klamath Tribes.

Why it matters

This wetland proves that converting farmland to marsh can clean polluted water and help endangered fish survive to adulthood.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2023-2024

Klamath River dam removal (2023-2024)

Four aging hydroelectric dams on the Klamath River were removed—the largest dam removal project in U.S. history—reopening 400 miles of habitat for salmon and steelhead.

Then

Salmon returned to historic spawning grounds within months; water quality improved.

Now

Set a precedent for large-scale river restoration and tribal co-management of waterways.

Why this matters now

The dam removal and Lakeside Farms wetland are parallel parts of the Klamath Basin's ecological recovery, showing that both river and floodplain restoration are needed to revive native fish and bird populations.

1990s-present

Everglades restoration agricultural buffers (1990s–present)

Florida's Everglades, long polluted by agricultural runoff, saw the creation of vast stormwater treatment areas and buffer wetlands. These natural filters absorb phosphorus and nitrogen before water enters sensitive ecosystems.

Then

Reduced phosphorus loads in the Everglades, though recovery remains incomplete.

Now

Established 'treatment wetlands' as a standard tool for managing agricultural pollution at scale.

Why this matters now

Lakeside Farms applies the same principle on a much smaller scale, demonstrating that even a 70-acre wetland can measurably improve water quality and support endangered species.
