<strong>Lewis</strong> <strong>River</strong> Interpretive & Education Plan<br />

Today, the Yakama Nation consists of over 8,000 people. <strong>The</strong>y are a sovereign<br />

traditional Treaty tribe, with a government that consists of 14 elected Tribal<br />

Council members. <strong>The</strong>y operate a number of business enterprises, including a<br />

Cultural Center, a credit enterprise, an industrial park, a furniture factory, and<br />

an RV park.<br />

<strong>The</strong> Yakama Nation is deeply involved in stewardship of both reservation and<br />

Usual and Accustomary lands. <strong>The</strong>y have a well-developed fisheries program,<br />

and are represented in land-use and fisheries negotiations and decisions<br />

throughout the region. <strong>The</strong>y consider the lands of south-central Washington<br />

their sacred trust, given to them by the Creator to hold and protect for future<br />

generations.<br />

Commission<br />

Before the construction of Yale and Swift dams, Pacific Power contracted with<br />

archaeologists to research and catalog sites of archaeological interest in the area.<br />

No large-scale prehistoric evidence was found, but researchers discovered a<br />

number of significant sites, including scatters of stone tools and tool flakes, and<br />

sites with ground stone tools (indicating vegetable material processing) and what<br />

appeared to be the remains of pit houses. To protect their integrity, none of these<br />

sites should be publicized.<br />

Further background on Native American use of this area and archaeological<br />

investigation of the sites of Yale and Swift Lakes is provided in <strong>PacifiCorp</strong>’s<br />

<strong>Lewis</strong> <strong>River</strong> Historic Properties Management Plan. Due to the sensitive nature<br />

of archaeological sites, specific information on the location and nature of<br />

archaeological sites is not included in this storyline.<br />

Early Euroamerican<br />

Explorations<br />

<strong>The</strong> earliest documented travel by Euroamerican explorers through the <strong>Lewis</strong><br />

<strong>River</strong> Valley occurred in the mid-1800s. <strong>The</strong>se early explorers were primarily fur<br />

traders and entrepreneurs, and, after the discovery of gold on the <strong>Lewis</strong> (then<br />

called the “Cathlapoot’l”) in the early 1850s, prospectors. Most probably traveled<br />

at least in part via the “Klickitat Trail”—a route that went from Fort Vancouver<br />

to the Yakama area, in part via the <strong>Lewis</strong> <strong>River</strong>. According to maps and notes<br />

from George B. McClellan’s 1853 railway-survey expedition, the trail probably<br />

entered the <strong>Lewis</strong> drainage from Clehatchie Prairie and crossed the <strong>Lewis</strong> in the<br />

eastern third of what is now Lake Merwin, then ran up Speelyai Creek, rejoining<br />

the <strong>Lewis</strong> near the present-day site of Yale Dam. It then continued up the north<br />

side of the <strong>Lewis</strong> past present-day Swift Lake.<br />
