Iron Horse Creek Restoration Plan Targets 0.26 Acres of Stream and Meadow Habitat

IRON HORSE, Plumas County — November 3, 2026. A restoration plan for Iron Horse Creek near Portola was filed with California’s State Clearinghouse in May 2026. It concerns a small area of stream and adjacent meadow, not a countywide flood-control construction project.

What the work would include

The filing describes restoring roughly 0.26 acres of stream habitat, using 14 grade-control structures, channel-fill treatments and riparian revegetation. The stated purpose is to improve aquatic and streamside habitat, reconnect an incised channel with its floodplain and support groundwater recharge.

Who submitted the project?

The California Regional Water Quality Control Board published the environmental notice, and MTN Consulting and Restoration LLC is named as the applicant. The filing identifies a site near Iron Horse Drive in the Portola area and says the restoration qualifies for a categorical exemption for small habitat projects.

What the filing does not establish

Environmental approval and enrollment under a water-quality order are not proof that construction has been completed. Local readers can request before-and-after information, maintenance plans and final monitoring results from the project applicant or the regional water board to assess the ecological outcomes.
