Post Falls Dam
Post Falls Dam is a dam on the Spokane River in the city of Post Falls, Idaho. The current dam was constructed in 1906 on the site of an older wooden dam that was used to power a sawmill. Post Falls Dam is commonly referred to in the singular, but the facility actually contains three dams spanning three channels of the Spokane River as it navigates around the Avista Islands. It is the most-upstream dam on the Spokane River, just nine miles from its source at Coeur d'Alene Lake, and the first of seven total dams on the Spokane River. History The site of the Post Falls Dam was previously home to a 20-foot wooden diversion dam built by pioneer settler and namesake of Post Falls, Frederick Post, who purchased the land from Chief Andrew Seltice of the Coeur d'Alene Tribe for $500 in 1871. Post built his original dam to power a sawmill on the north channel of the river. The sawmill burned down in 1902 and the site was sold to Washington Water Power, now known as Avista Avista Cor ...

Spokane River
The Spokane River is a tributary of the Columbia River, approximately long, in northern Idaho and eastern Washington in the United States. It drains a low mountainous area east of the Columbia, passing through the Spokane Valley and the city of Spokane, Washington. Description The Spokane River drains the northern part of Lake Coeur d'Alene in the Idaho Panhandle, emptying into the Columbia River at Franklin D. Roosevelt Lake, approximately downstream.National Research Council, 2005p. 92/ref> From Lake Coeur d'Alene, the Spokane River traverses the Rathdrum Prairie until reaching Post Falls, Idaho where it passes over a Post Falls Dam, and a natural 40-foot waterfall. Continuing westward it passes over 6 more dams, three of which (Upriver Dam, Upper Falls Dam, Monroe Street Dam) are located in the city of Spokane. In Spokane, it flows over the Spokane Falls, which are located in the heart of Downtown Spokane, approximately one third of the way down the river's length. A ...

Coeur D'Alene Tribe
The Coeur d'Alene Tribe ( ; also Skitswish; ) are a Native American tribe and one of five federally recognized tribes in the state of Idaho. The Coeur d'Alene have sovereign control of their Coeur d'Alene Reservation, which includes a significant portion of Lake Coeur d'Alene and its submerged lands. In '' Idaho v. United States'' (2001), the United States Supreme Court ruled against the state's claim of the submerged lands of the lower third of Lake Coeur d'Alene and related waters of the St. Joe River. It said that the Coeur d'Alene were the traditional owners and that the Executive Branch and Congress had clearly included this area in their reservation, with compensation for ceded territory. This area was designated in 1983 by the Environmental Protection Agency as Bunker Hill Mine and Smelting Complex, the nation's second-largest Superfund site for cleanup. Concerned at the slow pace of progress, in 1991 the tribe filed suit against mining companies for damages and clean ...

List Of Dams In The Columbia River Watershed
There are more than 60 dams in the Columbia River watershed in the United States and Canada. Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below. The dams are listed in the order as they are found from source to terminus. Many of the dams in the Columbia River watershed were not created for the specific purposes of water storage or flood protection. Instead, the primary purpose of many of these dams is to produce hydroelectricity. As can be seen in the lists, these dams provide many tens of gigawatts of power. Major dam construction began in the early 20th century and picked up the pace after the Columbia River Treaty in the 1960s, by the mid 1980s all the big dams were finished. Including just the dams listed below, there are 169 dams in the watershed, with 14 on the Columbia, 20 on the Snake, seven on the Kootenay, seven on the Pend Oreille / Clark, two on the Flathead, eight on the Yakima ...

Dams On The Spokane River
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Hydroelectric Power Plants In Idaho
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
