(ca) سد وادي جلين يقع على نهر كولورادو بولاية أريزونا شمال الولايات المتحدة الأمريكية. وقد تم بناء السد لتوفير الطاقة الكهرومائية، وكذلك لتنظيم تدفق حوض مياه نهر كولورادو العلوي إلى الحوض السفلي للنهر. ويُسمى مستودع السد "بحيرة باول"، وتعد ثاني أكبر بحيرة اصطناعية في أمريكا.وقد تم اقتراح بناء السد في عام [[1950م]] كجزء صغير من مشروع نهر كولورادو لتخزين المياه، وقد كان الغرض الرئيسي من المشروع توفير خزان للمياه لضمان توفير المياه الكافية للناس، خاصة في وقت امتدت في سنوات من الجفاف. وقد تم البدء في بناء السد في عام 1956م، ولم يتم الانتهاء منه إلا في عام 1966م، وعندما امتلأ خزان السد بدأ السد في السماح للمياه بالتدفق عبره إلى بحيرة باول، وقد تم تحويل الطاقة المائية إلى كهربائية بنجاح. وفي عام 1983 أدت فيضانات كبيرة داهمت السد إلى انهياره، وقد نتج عن ذلك فيضانات كبيرة في كولورادو.

Ausgehend vom Stauinhalt ist der entstandene Stauraum, der Lake Powell, nach dem Lake Mead der zweitgrößte Stausee der USA. (de) Glen Canyon Dam is a concrete arch-gravity dam on the Colorado River in northern Arizona, United States, near the town of Page. The 710-foot (220 m) high dam was built by the U.S. Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than 25 million acre-feet (31 km3). The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat. A dam in Glen Canyon was studied as early as 1924, but these plans were initially dropped in favor of the Hoover Dam (completed in 1936) which was located in the Black Canyon. By the 1950s, due to rapid population growth in the seven U.S. and two Mexican states comprising the Colorado River Basin, the Bureau of Reclamation deemed the construction of additional reservoirs necessary. Contrary to popular belief, Lake Powell was not the result of negotiations over the controversial damming of the Green River within Dinosaur National Monument at Echo Park; the Echo Park Dam proposal was abandoned due to nationwide citizen pressure on Congress to do so. The Glen Canyon Dam remains a central issue for modern environmentalist movements. Beginning in the late 1990s, the Sierra Club and other organizations renewed the call to dismantle the dam and drain Lake Powell in Lower Glen Canyon. Today, Glen Canyon and Lake Powell are managed by the U.S. Department of the Interior within Glen Canyon National Recreation Area. Since first filling to capacity in 1980, Lake Powell water levels have fluctuated greatly depending on water demand and annual runoff. The operation of Glen Canyon Dam helps ensure an equitable distribution of water between the states of the Upper Colorado River Basin (Colorado, Wyoming, and most of New Mexico and Utah) and the Lower Basin (California, Nevada and most of Arizona). During years of drought, Glen Canyon guarantees a water delivery to the Lower Basin states, without the need for rationing in the Upper Basin. In wet years, it captures extra runoff for future use. The dam is also a major source of hydroelectricity, averaging over 4 billion kilowatt hours per year. The long and winding Lake Powell, known for its scenic beauty and recreational opportunities including houseboating, fishing and water-skiing, attracts millions of tourists each year to the Glen Canyon National Recreation Area. In addition to its flooding of the scenic Glen Canyon, the dam's economic justification was questioned by some critics. It became "a catalyst for the modern environmental movement," and was one of the last dams of its size to be built in the United States. The dam has been criticized for the large evaporative losses from Lake Powell and its impact on the ecology of the Grand Canyon, which lies downstream; environmental groups continue to advocate for the dam's removal. Water managers and utilities state that the dam is a major source of renewable energy and provides a vital defense against severe droughts. (en) La presa del Cañón de Glen (en inglés, Glen Canyon Dam) es la segunda presa en tamaño del río Colorado en Page (Arizona), Estados Unidos. El principal propósito de la presa incluye generar energía hidroeléctrica, almacenar agua para los áridos Estados Unidos del suroeste, y proporcionar oportunidades de recreación en el agua. La presa genera una media de 451 megavatios, que contribuye al 6% de la electricidad total generada en Arizona. Un 13% de la electricidad generada en Utah, en donde se encuentra la mayor parte del lago Powell, calcula a una cifra que ahorra alrededor de cinco toneladas métricas de dióxido de carbono. La presa tiene una capacidad máxima de mil trescientos megavatios pero solo utiliza una media de 451 megavatios. El represado del río Colorado hizo que el , que queda al norte de la presa, se inundase y posteriormente ha creado un gran embalse llamado lago Powell. La presa de Glen Canyon se encuentra corriente arriba del Parque nacional del Gran Cañón y tiene un arco de presa de cemento de 216 metros de alto que controla el fluir del agua de las cuencas superior e inferior del río Colorado. La presa controla una cuenca hidrológica de 281.671 kilómetros cuadrados y también funciona como una barrera para los organismos acuáticos corriente arriba y abajo. Una de 2.280 megavatios, alimentada por carbón, se encuentra también en la zona cercana. * Vista de frente * Turbina * Central eléctrica (es) Le barrage de Glen Canyon est situé sur le Colorado dans l'Arizona, au sud-ouest des États-Unis, près de la ville de Page dans le comté de Coconino.

(nl) Zapora Glen Canyon (ang. Glen Canyon Dam) – betonowa zapora wodna typu grawitacyjno-łukowego, zbudowana w kanionie na rzece Kolorado w Stanach Zjednoczonych w pobliżu miasta Page (Arizona). Zapora mieści się w stanie Arizona, pobliżu granicy z Utah i tworzy olbrzymi zbiornik retencyjny - jezioro Powella, znajdujący prawie w całości na terenie stanu Utah. Tama ma wysokość 220 m i długość 480 m, a do jej zbudowania zużyto 3 750 000 m³ materiału. Budowę rozpoczęto 15 października 1956 roku i zanim budowniczowie zorganizowali tymczasową przeprawę na drugi brzeg musieli dojeżdżać przez najbliższy most - Nawajo Bridge pokonując trasę około 320 km. Do budowy użyto około 400 000 bloków betonu, z których każdy ważył 24 tony. Budowę ukończono w 1966 roku. Uroczyste otwarcie miało miejsce 22 września w obecności ówczesnej Pierwszej Damy - Lady Bird Johnson. (pl) Glen Canyon Dam är en valvdamm i betong som dämmer upp Coloradofloden i norra Arizona i USA, nära staden Page. Dammen byggdes för att ge vattenkraft och reglera flödet från Coloradoflodens övreavrinningsområde till det nedre. Reservoaren är den näst största konstgjorda sjön i landet och sträcker sig uppför floden och in i staten Utah. Dammen är döpt efter Glen Canyon, en rad kraftigt färgade raviner varav de flesta nu ligger under vatten. Dammen föreslogs på 1950-talet som en del av ett federalt vattenprojekt, under ledning av (USBR). Avsikten var att skapa reservoarer i den övre delen av Coloradofloden och flera av dess större bifloder. Projektets huvudsyfte var att förbättra utnyttjandet av vattenföringen det övre avrinningsområdet som hade avtalats år 1922 i ett avtal mellan sju delstater, den så kallade Colorado River Compact. Ett annat syfte var att skapa en vattenreservoar för att säkerställa att nedre avrinningsområdet fick nog vatten under torrår. Det uppstod dock problem när USBR föreslog att bygga dammar i den federalt skyddade Echo Park Canyon i Utah. Efter en lång rad rättsliga strider med miljöorganisationer, som exempelvis , klubbades en plan igenom med en hög damm vid Glen Canyon. Bygget av Glen Canyon Dam påbörjades 1956 och var inte klar förrän 1966. När reservoaren fylldes började dammen att leverera ett stabilt och reglerat vattenflöde nedströms och producerade el till regionen. Under första halvåret 1983 gav kraftiga vårregn och stor snösmältning maximal avrinning till Coloradofloden. Felaktiga väderprognoser bidrog till att vattennivån i dammen inte sänktes tillräckligt inför det kommande höga flödet. I juni forsade vattnet in med mer än 3 400 m3/s. Trots att kraftverket kördes på full kapacitet fortsatte Lake Powell att stiga till en punkt där man tvingades öppna utskoven. Det är den enda gången utskoven har använts bortsett från några korta tester i 1980. Den överhängande katastrofen avvärjdes dock med liten marginal. Genom att kontrollera översvämningar och andra faktorer som en gång kännetecknade Coloradofloden har dammen allvarligt påverkat fysiska och ekologiska förändringar i den nedre delen av floden.

The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat. (en) La presa del Cañón de Glen (en inglés, Glen Canyon Dam) es la segunda presa en tamaño del río Colorado en Page (Arizona), Estados Unidos. El principal propósito de la presa incluye generar energía hidroeléctrica, almacenar agua para los áridos Estados Unidos del suroeste, y proporcionar oportunidades de recreación en el agua. La presa genera una media de 451 megavatios, que contribuye al 6% de la electricidad total generada en Arizona. Un 13% de la electricidad generada en Utah, en donde se encuentra la mayor parte del lago Powell, calcula a una cifra que ahorra alrededor de cinco toneladas métricas de dióxido de carbono. La presa tiene una capacidad máxima de mil trescientos megavatios pero solo utiliza una media de 451 megavatios. El represado del río Colorado hizo que el , que queda (es) Zapora Glen Canyon (ang. Glen Canyon Dam) – betonowa zapora wodna typu grawitacyjno-łukowego, zbudowana w kanionie na rzece Kolorado w Stanach Zjednoczonych w pobliżu miasta Page (Arizona). Zapora mieści się w stanie Arizona, pobliżu granicy z Utah i tworzy olbrzymi zbiornik retencyjny - jezioro Powella, znajdujący prawie w całości na terenie stanu Utah. (pl) Glen Canyon Dam är en valvdamm i betong som dämmer upp Coloradofloden i norra Arizona i USA, nära staden Page. Dammen byggdes för att ge vattenkraft och reglera flödet från Coloradoflodens övreavrinningsområde till det nedre. Reservoaren är den näst största konstgjorda sjön i landet och sträcker sig uppför floden och in i staten Utah. Dammen är döpt efter Glen Canyon, en rad kraftigt färgade raviner varav de flesta nu ligger under vatten. (sv) ГЕС Глен-Каньйон — гідроелектростанція у штаті Аризона (Сполучені Штати Америки). Знаходячись перед Греблею Гувера, становить верхній ступінь каскаду на річці Колорадо (на території Мексики впадає до Каліфорнійської затоки). Пригреблевий машинний зал обладнаний вісьмома турбінами типу Френсіс потужністю по 165 МВт, які працюють при напорі у 155 метрів та забезпечують виробництво 3,2 млрд кВт·год електроенергії на рік.
