Below the Cowlitz Falls Dam, the river enters Riffe Lake, a 23.5 mile long reservoir created by the 606-foot high Mossyrock Dam (RM 66), completed in 1968. Riffe Lake is operated as a storage reservoir by Tacoma Power for flood control and hydropower production. Due to characteristics of the dam and reservoir, no fish passage facilities have been constructed at Mossyrock Dam. A few miles below the dam, the river enters Mayfield Lake, a 13.5 mile long reservoir created by the construction of Mayfield Dam (RM 52) in 1962. Historically, the portion of the stream inundated by the three reservoirs was made up of a series of deep canyons. The salmon hatchery Barrier Dam (RM 49.5) located below Mayfield Dam is a collection facility for trapping and hauling fish into the upper basin, a practice that has been in effect since 1969. \n•\tThe upper portion of the subbasin (above Mayfield Dam) historically supported thousands of fall Chinook, spring Chinook, coho, and winter steelhead. Today, numbers of naturally spawning salmon and steelhead are limited to the adult returns associated with a program to reintroduce natural spawning salmon and steelhead above the hydrosystem. Hydropower development and operation have altered flows, habitat, and blocked passage of salmon and steelhead to their historical habitats. Spring Chinook, coho, and winter steelhead have been reintroduced into the upper Cowlitz habitats in recent years in an effort to reestablish natural salmon and steelhead production. Returns of spring Chinook, coho and winter steelhead include both natural and hatchery produced fish. \n•\tThe historical upper Cowlitz adult population is estimated from 20,000-70,000 fish with the majority of returns being late stock which spawn from late November to March. In 1948, WDF estimated coho escapement to the basin was 77,000; in the early 1950s, escapement to the basin was estimated as 32,500 coho. Current natural spawning returns are part of an upper Cowlitz and Cispus River reintroduction program. \n•\tCompletion of Mayfield Dam in 1962 blocked access above the dam; a returning adult trap and haul program began in 1994 where fish were collected below Mayfield Dam and released above Cowlitz Falls Dam, restoring some access to the upper watershed. \n•\tCowlitz origin hatchery coho are utilized for supplementation of natural coho. Natural spawning occurs in the mainstem and tributaries of the upper Cowlitz, Cispus, and Tilton rivers. Juvenile rearing occurs upstream and downstream of spawning areas. Juveniles rear for a full year in the Cowlitz Basin before migrating as yearlings in the spring. Juveniles are captured at the Cowlitz Falls Dam collection facility, acclimated at Cowlitz Salmon Hatchery and released into the lower Cowlitz. \n", "count" : "2" }, { "item" : "Stock origin is unresolved by the state and tribes.

WDFW conducted spawning surveys in 2005 and found eight redds in the upper North Fork Asotn, and sampled again in 2006 and found 9 redds in the upper North Fork and 3 redds in lower Cougar Creek. Electrofishing has produced fish in the 150 mm to 250 mm range, and redd size was indicative of the resident life history form.

Although fluvial bull trout are present in the mainstem of the upper Yakima River, they are infrequently encountered. Most bull trout that inhabit the upper Yakima River are likely fish that outmigrate from upper river tributaries and juvenile or sub-adult fish that are flushed out of upper river reservoirs during irrigation water releases. Fluvial bull trout grow and mature in the mainstem and then migrate during the late summer into upper tributaries to spawn. There are a few old catch records, some dating back to the 1930s, that indicate the presence of bull trout in Yakima River tributaries including Satus Creek, Cowiche Creek, Coleman Creek and the Cle Elum River.
