The resources of the project are strongly associated with the early development of electricity in the southern Oregon and northern California region and played a significant role in the area’s economy both directly, as a part of a regionally-significant, locally-owned and operated, private utility, and indirectly, through the role that increased electrical capacity played in the expansion of the timber, agriculture, and recreation industries during the first six decades of the 20th century. The Klamath Hydroelectric Project is considered regionally significant and eligible for listing in the National Register of Historic Places under Criterion “A” for its association with the industrial and economic development of southern Oregon and northern California.

  • Declining Sediment Loads from Redwood Creek and the Klamath River, North Coastal California
    Declining Sediment Loads from Redwood Creek and the Klamath River, North Coastal California Randy D. Klein1 and Jeffrey K. Anderson2 Abstract River basin sediment loads are affected by several factors, with flood magnitude and watershed erosional stability playing dominant and dynamic roles. Long-term average sediment loads for northern California river basins have been computed by several researchers by several methods. However, characterizing the dynamic nature of climate and watershed stability requires computation of annual loads. We computed annual suspended and bedload loads for the 1950s through 2009 for both Redwood Creek and the Klamath River. Results show high sediment loads coincident with a period of widespread logging by destructive practices and large storms in the 1950s through 1970s followed by a dramatic decline in sediment loads through the present. Analyses of annual departures from mean and time trend tests indicated the decline in loads is not due solely to the lack of very large storms. We infer it can also be explained by the partial recovery of watershed erosional stability from the 1980s through the present due to reduced logging rate, use of lower impact logging practices, and implementation of treatment programs for reducing erosional threats from logging roads. Key words: bedload, suspended load, watershed recovery, Redwood Creek, Klamath River Introduction Sediment yield, or load, consists of the total mass of sediment particles transported by streamflow past a location along a stream or river over a given time period. Sediment is transported either suspended in the water column (suspended load) or along the channel bed (bedload). Quantification of sediment loads can be important for a variety of management needs, such as evaluating land use impacts, reservoir design, coastal sediment budgets, and others.

  • After a Sleepless Full Moon Night With
    Restoring Coho Salmon in the Klamath River, One Beaver At A Time By Will Harling, Executive Director, Mid Klamath Watershed Council After a sleepless full moon night with our 18 month old daughter, Rory, (a night where my wife bore the brunt of her midnight antics and our guests sleeping in the living room must have been guessing who was torturing who), I bundled our girl onto my back and walked down to the Klamath River in the pre-dawn light. To say I altruistically wanted everyone to sleep in would be a half-truth given the fishing pole in one hand, balancing out the diaper bag in the other. I had a spot in mind, just downstream of the Orleans Bar River Access, where the river slides over a broad riffle so shallow the fish are forced into a narrow slot that one could cast across, even with a groggy, grumpy, sleep-deprived toddler strapped to their back. The relatively wide Orleans Valley gives the river a chance to meander a little here, reclaiming its sinuousity stolen over the past six million years as the Klamath Mountains began to rise from underneath, forcing it into steep sided canyons tracing fault lines in the uplifted bedrock just upstream and downstream of the valley. Fall chinook salmon moving upstream to spawn left wakes in the glassy water as they navigated up through the shallows, and the Klamath’s famed half-pounder steelhead run was coming in with them. Across the river, I noticed a furry head moving slowly upstream. The light brown tuft of hair visible above the water looked like what I thought a beaver would look like, but couldn’t be sure.

  • YUROK TRIBE 190 Klamath Boulevard • Post Office Box 1027 • Klamath, CA 95548
    YUROK TRIBE 190 Klamath Boulevard • Post Office Box 1027 • Klamath, CA 95548 Yurok Tribe Written Testimony Regarding H.R. 5548, Fishery Failures: Urgently Needed Disaster Declarations Act January 14th, 2020 INTRODUCTION The Yurok Tribe is a federally recognized Indian tribe whose reservation is located on the Lower Klamath River in Northern California, spanning from the river’s mouth at the Pacific Ocean upriver to the Yurok village of Weitchpec. With more than 6,300 tribal members, the Yurok Tribe is the largest Indian tribe in California. The fishery resources of the Klamath and Pacific Ocean are the mainstay of the life, economy, and culture of the Yurok Tribe. See Mattz v. Arnett, 412 U.S. 481, 486-87 (1973). The Klamath River Indian fishery is “not much less necessary to the existence of the [Yurok] Indians than the atmosphere they breathed.” Blake v. Arnett, 663 F.2d 906, 909 (9th Cir. 1981). A pillar of the Tribe’s legal rights is its federally reserved fishing right which was reserved in the creation of the Yurok Reservation. The Tribe enjoys commercial, subsistence, and ceremonial fishing rights on the lower 45 miles of the Klamath River which it exercises each year under strict regulation by the Yurok Tribal Government. See, Baley v United States, No. 18- 1323 (Fed. Cir. Nov. 14, 2019) (confirming Yurok fishing rights for commercial, subsistence, and ceremonial purposes). In this way, the Tribe maintains its fishing way of life. Tribal members are able to fish commercially to provide financial stability to their families, 1 ceremonially to support ancient practices necessary to maintain Yurok world balance, and for subsistence purposes to continue a fishing way of life.

  • Distribution of Anadromomous Fishes in the Upper Klamath River
    Distribution of Anadromomous Fishes in the Upper Klamath River Watershed Prior to Hydropower Dams— A Synthesis of the Historical Evidence fisheries history Knowledge of the historical distribution of anadromous fish is important to guide man- agement decisions in the Klamath River including ongoing restoration and regional recovery of coho salmon (Oncorhynchus kisutch). Using various sources, we determined the historical distribution of anadromous fish above Iron Gate Dam. Evidence for the feature largest, most utilized species, Chinook salmon (Oncorhynchus tshawytscha), was avail- ABSTRACT able from multiple sources and clearly showed that this species historically migrated upstream into tributaries of Upper Klamath Lake. Available information indicates that the distribution of steelhead (Oncorhynchus mykiss) extended to the Klamath Upper Basin as well. Coho salmon and anadromous lamprey (Lampetra tridentata) likely were distributed upstream at least to the vicinity of Spencer Creek. A population of anadro- mous sockeye salmon (Oncorhynchus nerka) may have occurred historically above Iron Gate Dam. Green sturgeon (Acipenser medirostris), chum salmon (Oncorhynchus keta), pink salmon (Oncorhynchus gorbuscha), coastal cutthroat trout (Oncorhynchus clarki clarki), and eulachon (Thaleichthys pacificus) were restricted to the Klamath River well below Iron Gate Dam. This synthesis of available sources regarding the historical extent of these species’ upstream distribution provides key information necessary to guide management and habitat restoration efforts. Introduction John B. Hamilton Gary L. Curtis Gatschet’s statement is that salmon ascend the Klamath river twice a year, in June and again in autumn. This is in agreement with my information, that the run comes in the middlefinger Scott M. Snedaker month [sic], May–June, and that the large fish run in the fall...They ascend all the rivers David K.
