Garrett County is the westernmost county of the U.S. state of Maryland completely within the Appalachian Mountains. As of the 2020 census, the population was 28,806, making it the third-least populous county in Maryland. Its county seat is Oakland. The county was named for John Work Garrett (1820–1884), president of the Baltimore and Ohio Railroad. Created from Allegany County in 1872, it was the last county to be formed in the state.
The Lower Colorado River Authority (LCRA) is a nonprofit public utility created in November 1934 by the Texas Legislature. LCRA's mission is to enhance the lives of the Texans it serves through water stewardship, energy and community service. LCRA provides public power, manages the lower Colorado River, builds and operates transmission lines, owns public parks, and offers community services.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Youghiogheny River, or the Yough for short, is a 134-mile-long (216 km) tributary of the Monongahela River in West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is a Lenape word meaning "a stream flowing in a contrary direction".
Deep Creek Lake State Park is a public recreation area occupying more than 1,100 acres (450 ha) on the northeast side of Deep Creek Lake in Garrett County, Maryland, in the United States. The park features water activities, camping facilities, and recreational trails and is located about 18 miles (29 km) south of Interstate 68 on U.S. Route 219.
Deep Creek Lake is a man-made reservoir in the U.S. state of Maryland. It covers about 3,900 acres (16 km2) and has 69 miles (111 km) of shoreline. The lake is home to a wide variety of aquatic life, such as freshwater fish and aquatic birds. The Wisp Ski Resort is located nearby.
Holtwood Dam is the oldest of three major dams built across the lower Susquehanna River, and the middle location of the three. It was constructed as the McCalls Ferry Dam between 1905 and 1910 by the Pennsylvania Water & Power (PW&P) Company. The dam was renamed Holtwood in honor of two company executives. PW&P merged with Pennsylvania Power & Light (PPL) in 1955. In 2015 Talen Energy took over PPL's generation and immediately sold the Holtwood plant to Brookfield Renewable Energy Partners to comply with federal antitrust requirements.
The Safe Harbor Dam is a concrete gravity dam, with an associated hydroelectric power station, on the lower Susquehanna River. It is the most northerly and last of three Great Depression-era public electrification projects' hydroelectric dams, and was constructed between April 1, 1930, and December 7, 1931. It created a long and relatively shallow lake, known as Lake Clarke, along the upper stretch of the Conejohela Valley. The creation of the lake shrank the upper Conejohela Flats in size.
Lar Dam is a dam located at the foot of Mount Damavand in Amol county, Mazandaran, Iran. The dam is located within the protected Lar National Park, and situated just 70 kilometers northeast of the capital and the most populous city of the country, Iran. The primary purpose of the dam is municipal water supply to Tehran but prior to the water reaching the city filtration plant, it is used to power the Kalan and Lavarak Hydroelectric Power Stations, with a combined installed capacity of 162.5 MW.
Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island.
The Youghiogheny Scenic & Wild River is a river given special protected status by the state of Maryland. This wild and scenic portion of the Youghiogheny River is located in Western Garrett County, in Western Maryland. The Yough drains an area comprising approximately 397 square miles (1,030 km2) in Maryland, flowing through forests and farms. It rises from the west side of Backbone Mountain in Preston County, West Virginia, near the state's border with Garrett County.
Lac des Mille Lacs is a lake in the western part of Thunder Bay District in northwestern Ontario, Canada. It is in the Nelson River drainage basin and is the source of the Seine River. The lake lies between Ontario Highway 17 on the north and Ontario Highway 11 on the south about 100 kilometres (62 mi) west of the city of Thunder Bay.
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity in the United States. In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity.
The Groundhog River is a river in Cochrane District and Sudbury District in Northeastern Ontario, Canada. The river is in the James Bay drainage basin and is a left tributary of the Mattagami River.
Harris Station Dam is a hydroelectric dam in Northeast Somerset, Somerset County, Maine. Also known as the Indian Pond Project, the dam was built from 1952 to 1954 as the largest hydroelectric dam in the state of Maine. It impounds the Kennebec River at the southern end of the natural Indian Pond, about 12 miles (19 km) downstream from Moosehead Lake.
The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). The use and reuse of the waters of the San Joaquin River, its South Fork, and the namesake of the project, Big Creek – over a vertical drop of 6,200 ft (1,900 m) – have over the years inspired a nickname, "The Hardest Working Water in the World".
The Seyrantepe Dam is an earth-fill embankment dam on the Peri River, located 15 km (9 mi) northwest of Karakoçan on the border of Elazığ and Tunceli Provinces, Turkey. Its primary purpose is hydroelectric power generation and is the fifth dam in the Peri River cascade. Construction on the dam began in 2003 and its power station was commissioned in 2008. It contains two 29.39 MW Francis turbine-generators for a total installed capacity of 58.78 MW. It is owned and operated by Limak Energy and Bilgin Energy. The sand and gravel-fill dam is 48.5 m (159 ft) tall.
The Koma Kulshan Project is a 13.3 MW run-of-the-river hydroelectric generation facility on the slopes of Mount Baker, a stratovolcano in Washington state's North Cascades. The project commenced commercial operation in October 1990, and is owned by a Covanta Energy–Atlantic Power joint venture. It supplies Puget Sound Energy via a Power Supply Agreement (PSA) contract. Its single turbine is a Pelton wheel supplied by Sulzer Escher Wyss.
