Cold Creek (Russian River Tributary)
Cold Creek is a river of Mendocino County, California, a tributary of East Fork Russian River. In the past it may have connected Clear Lake to the Russian River before this route was blocked by a large landslide and Clear Lake began to drain into the Sacramento River watershed. Location Cold Creek is long. It is a left tributary of East Fork Russian River. The Ukiah Valley extends up the Russian River to the junction of the east fork with the main stream. Above this along the east fork to the confluence of Cold Creek it is known as Coyote Valley (''cō'dakai''). Above Cold Creek to the head of the east fork it is called Potter Valley (''djūhū'la-kai''). A 1914 survey of the Ukiah Area said the Cold Creek Valley was small and not very important agriculturally. It was interesting because it belonged to a middle-aged stream that was now tributary to a very youthful stream. The East Fork of the Russian River has a youthful topography, flowing with a high gradient through a V-sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clear Lake Volcanic Field
The Clear Lake Volcanic Field is a volcanic field beside Clear Lake in California's northern Coast Ranges. The site of late-Pliocene to early Holocene activity, the volcanic field consists of lava domes, cinder cones, and maars with eruptive products varying from basalt to rhyolite. The site's threat level is ranked "High" at #33 in the top volcanic threats in the United States according to "2018 Update to the U.S. Geological Survey National Volcanic Threat Assessment". The last eruption being about 11,000 years ago. Cobb Mountain and Mount Konocti are the two highest peaks in the volcanic field, at . Retrieved 2008-08-19. and respectively. The field's magma chamber also powers a geothermal field called The Geysers, which hosts the largest complex of geothermal power plants in the world. These can generate approximately 2000 megawatts, enough to power two cities the size of San Francisco. The Clear Lake volcanics are thought to have been the heat source for the hot springs ...

Eel River (California)
The Eel River (Wiyot: ''Wiya't''; Cahto: ''Taanchow''; Northern Pomo: ''ch'idiyu'') is a major river, about long, of northwestern California. The river and its tributaries form the third largest watershed entirely in California, draining a rugged area of in five counties. The river flows generally northward through the Coast Ranges west of the Sacramento Valley, emptying into the Pacific Ocean about downstream from Fortuna and just south of Humboldt Bay. The river provides groundwater recharge, recreation, and industrial, agricultural and municipal water supply.William M. Brown and John R. RitterSediment transport and Turbidity in the Eel River Basin, 1971, prepared in cooperation with the California Department of Water Resources, 67 pages The Eel River system is among the most dynamic in California because of the region's unstable geology and the influence of major Pacific storms.

Potter Valley Project
The Potter Valley Project is an interbasin water transfer project in Northern California in the United States, delivering water from the Eel River basin to turbines in the headwaters of the Russian River. The project is owned and operated by Pacific Gas and Electric Company (PG&E). The main facilities are two dams on the Eel River, a diversion tunnel and hydroelectric plant. Average annual throughput is , although this figure varies significantly with both the amount of precipitation in the Eel River basin and the demand on the Russian River. In 2019, PG&E chose not to relicense the hydroelectric project with the Federal Energy Regulatory Commission, as it had become unprofitable to operate. Federal regulations require that PG&E submit a final license surrender application by 2025, which would enable it to begin decommissioning the project. The dams and hydroelectric facilities are to be removed, while various options are being considered for maintaining water diversions to the ...

Scotts Creek (California)
Scotts Creek is a stream in Lake County, California, the largest tributary of Clear Lake. It rises to the south of Cow Mountain in the Mayacamas Mountains, then flows southeast towards Clear Lake, running through the fertile Scotts Valley and the seasonal Tule Lake before joining Middle Creek and flowing into the lake via Rodman Slough. Hydrology Scotts Creek is long. It is the largest tributary of Clear Lake, contributing about 24% of the streamflow to the lake with a watershed that covers 23% of the Clear Lake basin. Clear Lake drains to the east via Cache Creek to the Sacramento River. The course of Scotts Creek resembles a letter "S" with its vertical axis tilted 45° clockwise. The creek forms to the south of Cow Mountain, and then runs southeast to its junction with the creek's South Fork. It turns east and then northeast past Lakeport, then flows northwest through the fertile Scotts Valley up to the outlet from the Blue Lakes. From this point it turns east and flo ...

Northern Pomo
Northern Pomo is a critically endangered Pomoan language, spoken by the indigenous Pomo people in what is now called California. The speakers of Northern Pomo were traditionally those who lived in the northern and largest area of the Pomoan territory. Other communities near to the Pomo were the Coast Yuki, the Huchnom, and the Athabascan.Barrett, Samuel A. (1908). The Ethno-Geography of the pomo and neighboring indians'.

Cache Creek (Sacramento River Tributary)
Cache Creek is an U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 10, 2011 stream in Lake, Colusa and Yolo counties, California. Course Cache Creek starts at the outlet of Clear Lake. It has two main tributaries: North Fork (starting in the Mendocino National Forest north of Clear Lake, and dammed by the Indian Valley Reservoir); and Bear Creek (starting in Bear Valley). The Capay Diversion Dam, west of Capay, diverts water for distribution throughout Yolo County using a network of canals. At the end of the Capay Valley, near Esparto, Cache Creek runs east into Sacramento Valley, ending in a settling basin east of Woodland, the overflow of which runs into the Sacramento River through a flood control canal. In addition to the recreational use of Clear Lake and Indian Valley Reservoir there are numerous trail-heads, parks and campgrounds, including the Bear Valley wildflower hotspot.

Blue Lakes (California)
The Blue Lakes are a string of two or three lakes in Lake County, California, set in a deep canyon. At one time they seem to have been in the Russian River watershed, but a recent geological upheaval cut them off from that basin and they now drain via Scotts Creek into Clear Lake in the Sacramento River basin. In the 19th and early 20th centuries there were several resorts around the lakes. Their waters have been highly altered by human activity and most of their native fish are lost, but they have a healthy population of largemouth bass. Location The Blue Lakes are in the Cache Creek watershed in northwestern Lake County, about west of Upper Lake. Their drainage basin comprises the upper northwest section of the Cache Creek basin. They are at an elevation of . Upper Blue Lake is about above sea level, covers about and contains about of water. Lower Blue Lake is shallower and covers . The Köppen climate classification is Csb : Warm-summer Mediterranean climate. The Blue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian River (California)
The Russian River (Southern Pomo: ''Ashokawna'', es, Río Ruso) is a southward-flowing river that drains of Sonoma and Mendocino counties in Northern California. With an annual average discharge of approximately 1,600,000 acre feet (2.0 km3), it is the second-largest river (after the Sacramento River) flowing through the nine-county Greater San Francisco Bay Area, with a mainstem long. Names The Southern Pomo know the river as Ashokawna (ʼaš:oʼkʰawna), "east water place" or "water to the east", and as Bidapte, "big river". Juan Rodríguez Cabrillo and his expedition may have travelled as far north as the Russian River in November 1542 before storms forced them to turn back south towards Monterey. The earliest Slavic name for the river, Slavyanka, appears on a Russian-American Company chart dated 1817. In 1827 the Spanish called it the San Ygnacio, and in 1843 the Spanish land grant referred to it as Rio Grande. The river takes its current name from Russian Iv ...

East Fork Russian River
East Fork Russian River is a long tributary of the Russian River in Mendocino County, California artificially connected to the Eel River via an interbasin diversion at the Potter Valley Project hydroelectric facility. It forms in the north of Potter Valley, flows south through this valley, then southwest through a mountain pass to Lake Mendocino, an artificial reservoir that empties into Russian River. At one time Clear Lake to the east drained through Cold Creek then along the lower part of East Fork Russian River through Coyote Valley to the Russian River proper. A few hundred years ago a massive landslide blocked this channel, and Clear Lake found a new outlet to the Sacramento River. Cold Creek flows year round, while the upper part of East Fork Russian River used to dry up in the summer leaving isolated pools along its course. This changed when the Potter Valley Project was completed in 1908. The project involved construction of two reservoirs on Eel River to the north of ...

California Regional Water Quality Control Board
The California State Water Resources Control Board (SWRCB) is one of six branches of the California Environmental Protection Agency. History This regulatory program has had the status of an official government department since the 1950s. The State Water Pollution Control Board, as well as 9 regional boards, were established by the Dickey Water Pollution Act of 1949. The board was renamed to the State Water Quality Control Board by an Act of 1963. The State Water Resources Control Board was established from the State Water Quality Control Board and the State Water Rights Board by an Act of 1967. California's pioneering clean water act is the 1969 Porter-Cologne Water Quality Control Act (Porter-Cologne Act). Through the Porter-Cologne Act, the State Water Board and the Regional Water Boards have been entrusted with broad duties and powers to preserve and enhance all beneficial uses of the state's immensely complex waterscape. The Porter-Cologne Act is recognized as one of the nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potter Valley, California
Potter Valley is a census-designated place in Mendocino County, California, United States. It is located north-northeast of Ukiah, at an elevation of at the headwaters of the East Fork Russian River. The CDP population was 665 at the 2020 census. History In 1852, when William and Thomas Potter and Mose Briggs first entered what would become known as Potter Valley, they were searching for the headwaters of the Russian River from their base in Sonoma County. The Pomo people called it ''Ba-lo Kai''. They found three Pomo villages (each about 500 people strong), the Russian headwaters, and a lush valley with wild oats "stirrup high". Eventually the Potters returned to settle there, and the valley became known by the American ranchers' name. The post office opened in 1870. Painter Grace Hudson was born in Potter Valley in 1865. In addition to his famous Ridgewood Ranch, Charles S. Howard, owner of the racehorse Seabiscuit, owned a ranch in Potter Valley where he ran cattle. Ge ...
