Gold Hill Irrigation District Improves Fish Passage At Dam On Rogue River

Gold Hill Lamprey Salvage

The Gold Hill Irrigation District operates a diversion dam on the Rogue River near the town of Gold Hill. The diversion dam and canal, which supplies the community with irrigation water, had been virtually unchanged since 1916. Design flaws meant that many migratory fish were diverted along with the irrigation water, ending up in an irrigation canal where they were easy prey for bird and mammal predators.

In partnership with Freeways for Fish, the Gold Hill Irrigation District undertook a major upgrade and restoration project that improved safety for migrating fish at the site. Together, we

  • Decreased the amount of water and the number of fish diverted out of the Rogue River without affecting the District’s water right
  • Returned diverted fish to the Rogue River quickly by replacing an open ditch with a pipe, eliminating the risk of predation in the canal environment
  • Removed a canal overflow area that attracted adult fish away from the Rogue River

Wagner Creek Diversion Structure To Be Replaced With Fish-Friendly Design

Wagner Creek Diversion Structure

Geos Institute recently completed landowner and water user agreements with 19 parties that will allow the replacement of a diversion structure on Wagner Creek near Talent, Oregon, with a structure that will allow fish of all size to pass quickly and safely. The existing structure is old, leaky, and nearly impossible for fish to migrate past during spring, summer, and fall months. Even during winter, water flows must be just right to permit adult fish to pass. Geos Institute is now working with Cascade Stream Services to design a structure that will allow the water users to continue diverting their water right while also allowing even small fish to swim past the site under all but the most extreme flow conditions.

Little Butte Creek Remeander

Little Butte Creek Restored Channel aerial

The lower reaches of Little Butte Creek were once among the most important salmon producing tributaries in the Rogue Basin. Around 1950, however, much of meandering Little Butte Creek was straightened, with disastrous consequences for native fish. Freeways for Fish worked directly with the Oregon Department of Fish & Wildlife, River Design Group, Inc., L & S Rock Products, Inc. and several other local partners to restore stream flow to one meandering reach of Little Butte Creek in the Denman Wildlife Area near Medford, Oregon.

Gold Ray Dam Removed

For 106 years the Gold Ray Dam sat on the mainstem of the Rogue, just upstream from the town of Gold Hill, hindering the migration of native fish. In the early 1970s the hydroelectric dam became obsolete and ownership was transferred to Jackson County. It was considered a liability, so in the 2000s, Freeways for Fish worked alongside Jackson County and many other partner groups to determine the future of the Gold Ray Dam.

Studies conducted by the County justified removing the dam for biological, social, and economic advantages, as well as to reduce the county's liability. The Geos Institute helped Jackson County develop the dam removal plans, secure funding, and oversee the work. The dam was removed in early fall 2010, converting two miles of warm reservoir waters back to free-flowing current. For the first time in over a century, salmon and steelhead could travel unimpeded between the Pacific Ocean and the upper Rogue basin. Moreover, in true "if-you-remove-it-they-will-spawn" fashion, the stretch of river below the former reservoir has reworked itself over the past few years into an important spawning ground for fall Chinook.

Evans Creek Dam Removal

Wimer Dam Group ShotIn 2015, after many years of planning, the Fielder and Wimer dams – two of the worst fish impediments in the state of Oregon – were finally removed from Evans Creek, an important salmon and steelhead tributary of the Rogue River. Geos Institute acted as the project manager for both dam removals, technical projects involving a host of players, logistics, and permits. Now that these dams are gone, 16 miles of Chinook habitat, 60 miles of coho habitat, and more than 70 miles of steelhead habitat are once again open and accessible for local fish.
