TTY/TDD users should contact DES via the Washington Relay Service at 711 or 1-800-833-638 Biodiesel Use by Washington State Agencies January to December 2017 REPORT HIGHLIGHTS • During 2017, biodiesel purchased by state agencies under state fuel contracts reached a new high, totaling over 1.2 million gallons. This is the fifth year in a row that state agency biodiesel purchases topped 1 million gallons. • Washington State Ferries (WSF) is the largest state agency consumer of diesel fuel. WSF purchased 882,000 gallons of biodiesel during 2017, which is about 74,000 gallons more than that purchased in 2016. This increase was due primarily to overall increased fuel use. WSF averaged 4.7 percent biodiesel in 2017, up from 4.3 percent in 2016, with fuel containing 5 percent biodiesel (B5) the standard fuel for the fleet. • Beyond WSF operations, Washington State Department of Transportation (WSDOT) accounted for the state’s second largest purchaser of diesel fuel. WSDOT purchased 364,000 gallons of biodiesel (B100) during 2017, almost the same amount purchased in 2015 and 2016. Biodiesel made up 19 percent of total diesel fuel purchased in Western Washington and 10% percent in Eastern Washington. Statewide, WSDOT averaged 14 percent biodiesel, down 1 percent from 2016.

In 1941 the federal government dammed the Columbia River at the north endof Grand Coulee, creating a man-made reservoir named Lake Roosevelt that inundated homes, farms, and businesses, and disrupted the lives ofmany. Although Congress never enacted specific authorization to createa park, it passed generic legislation that gave the Park Service authorityat the National Recreation Area (NRA). Lake Roosevelt's shoreline totalsmore than 500 miles of cliffs and gentle slopes. The Lake Roosevelt NationalRecreation Area (LARO) was officially created in 1946. This historical study documents

    Corridor Sketch Summary Printed at: 4:08 PM 3/19/2018 WSDOT's Corridor Sketch Initiative is a collaborative planning process with agency partners to identify performance gaps and select high-level strategies to address them on the 304 corridors statewide. This Corridor Sketch Summary acts as an executive summary for one corridor. Please review the User Guide for Corridor Sketch Summaries prior to using information on this corridor: SR 25: US 2 Jct (Davenport) to US 395 Jct (Kettle Falls) This 81-mile long north-south corridor is located in eastern Washington running between Davenport and Kettle Falls. The corridor passes through the unincorporated communities of Fruitland, Hunters, Cedonia, Gifford, Daisy, and Rice. The corridor’s character between the cities of Davenport and Kettle Falls is rural with few single-family residences within each community, whereas Kettle Falls and Davenport are high density suburban. Other land uses along the corridor include agriculture and open space residential, private/commercial forest and public forest, and commercial retail and services around the communities of Fruitland, Hunters, Cedonia, Gifford, Daisy and Rice. Terrain near Davenport is level, all other corridor terrain is rolling. The corridor runs adjacent to the Columbia River, crosses over multiple creeks, and travels over the Spokane River. Davenport Municipal Airport is located in Davenport and the Eastern Washington Gateway and Kettle Falls International Railway are located at the southern and northern endpoint respectively. Vegetation on the corridor is comprised of deciduous and coniferous trees, shrub land, and long grasses. Current Function State Route 25, also known as the Coulee Reservoir Highway, links Davenport and Canada.

The construction of the dam permanently and forever blocked the once abundant anadromous fish runs to the upper Columbia Basin. Since the construction of Grand Coulee Dam in 1943 and Chief Joseph Dam in 1956 this area is known as the blocked area. The blocked area is totally dependant upon resident fish species to provide a subsistence, recreational and sport fishery. The sport fishery of lake Roosevelt is varied but consists mostly of Rainbow trout (Oncorhynchus mykiss), Kokanee salmon (Oncorhynchus nerka), Walleye (Stizostedion vitreum) Small mouth bass (Micropterus dolomieui) and white sturgeon (Acipenser transmontanus).

  • Cultural Resources
    Section III Identification of Cultural Resources 21 Archaeological Sites and Traditional Cultural Properties. Mount Spokane has only occasionally been a destination for archaeologists. Early archaeological research efforts in Washington State focused on large coastal shell middens or, in the interior, broad river valleys where archaeological sites were more plentiful and easily accessed. Archaeological investigations in the Spokane vicinity did not begin in earnest until 1940 when the Columbia Basin Archaeological Survey undertook efforts along the Spokane River in association with construction of Grand Coulee Dam (Collier, Hudson, and Ford 1942). Later in 1950, Louis Caywood of the National Park Service began work at the historic site of Fort Spokane, northwest of Spokane. The fort was a fur trade post erected in 1812 by employees of the Pacific Fur Company, an American fur trade company owned by John Jacob Astor. In his four seasons of fieldwork at Fort Spokane, Caywood exposed most of the fort's palisades, several of its interior features, and a nearby boat house (Caywood 1954). Work resumed at Fort Spokane in 1962 and 1963 when Richard Daugherty, Washington State University, continued archaeological excavations within the fort’s stockade. Daugherty also sought to further delineate the location of a second trading post known as Spokane House. The Hudson’s Bay Company erected Spokane House in 1810, nearly two years before the Pacific Fur Company erected Fort Spokane. The two trading posts were located next to each other for protection and as symbols of their respective countries political presence in the region (Combs 1964). Throughout the 1970s and 1980s, the Spokane Valley saw limited archaeological survey and excavation work.
