Where is yakima river

Millions of years ago, the Yakima was a slow, meandering river flowing through a flat basalt plain. Geologic pressure lifted and folded the basalt over many more millions of years. The Yakima River Canyon is a 20 mile stretch of the river between Ellensburg and Selah which was formed as three major ridges, Manashtash, Umtanum and Selah Butte, rose diagonally across the path of Yakima river.

This process was slow enough to allow the river to carve a path through the basalt, retain the ancient meanders and create the hills and sheer cliffs that we see in the Canyon today.

The Yakima River Canyon is a popular desination for birders, fly fishers, hikers, bikers not the safest ride for pedal bikes due to traffic and a narrow, winding roadway , photographers, campers, recreational floaters and sightseers. State Route , which parallels the river through the Canyon, was the first highway in Washington to be designated a state scenic byway The Conservancy established its Yakima River Canyon preserve in to protect the fragile and unique habitats there.

The preserve includes acres of basalt cliff as well as important grasslands and an island in the middle of the Yakima River. Cooperating with the U. Bureau of Land Management, The Nature Conservancy began a long-range protection program for the canyon with the acquisition of a acre parcel of grassland and cliff habitat in The program ensures the protection of plant and animal life, as well as scenic and recreational resources which significantly benefit the region's residents and economy.

The Nature Conservancy still retains of those acres. Two reaches were profiled twice resulting in The hydrogeologic framework was delineated for the ground-water flow system of the three basalt formations and two interbeds in the Yakima River Basin, Washington. The two major interbed units between the basalt formations generally are referred to as the Total 78, unique values. This grid made it easy to provide estimates of monthly ground-water recharge for water years Two models were used to estimate ground-water recharge to the Yakima River Basin aquifer system, Washington for predevelopment estimate of natural conditions and current a multi-year, , composite land-use and land-cover conditions.

A daily water-budget model for estimating ground-water recharge, the Deep Percolation Model, was modularized for inclusion into the U. Geological Survey's Modular Modeling System. The model was modularized in order to facilitate estimation of ground-water recharge under a large range in climatic, landscape, and land-use and land-cover conditions Ground-water pumpage in the Yakima River Basin, Washington, was estimated for eight categories of use for as part of an investigation to assess groundwater availability in the basin.

Methods used, pumpage estimates, reliability of the estimates, and a comparison with appropriated quantities are described. The eight categories of pumpage The hydrogeologic framework was delineated for the ground-water flow system of the sedimentary deposits in six structural basins in the Yakima River Basin, Washington.

The numerical model will be an integrated tool for daily to long-term water-resources management and for testing potential management strategies Relevance and Benefits - The study addresses many issues identified in the USGS Water Resources Division's strategic plan for meeting the Nation's water-resources needs. Below are publications associated with this project.

Local vineyards are crushing it, too. That should provide some cheer for the throngs of outdoor recreation lovers from Seattle and the Puget Sound looking to wet their whistles after a day on the playground that surrounds the Yak.

Downstream, wild trout are the main attraction, but steelhead and salmon are the real story. Salmon that had been absent from the Yakima River Basin for more than years due to impassable dams are making their return in increasing numbers.
