Lagunitas Creek
Lagunitas Creek is a -longU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed December 27, 2017 northward-flowing stream in Marin County, California. It is critically important to the largest spawning runs of endangered coho salmon (''Oncorhynchus kisutch'') in the Central California Coast Coho salmon Evolutionary Significant Unit (CCC ESU). The stream's headwaters begin on the northern slopes of Mount Tamalpais in the Coast Range and terminate in southeast Tomales Bay, northwest of Point Reyes Station, California. Lagunitas Creek feeds several reservoirs on Mt. Tamalpais that supply a major portion of the county's drinking water. History To the Coast Miwok the stream was known as Tokelalume, then by the Spanish as Arroyo de San Geronimo, then Daniels creek. Now the "San Geronimo" survives only as the San Geronimo Creek tributary. The modern name, Lagunitas Creek, is derived from the several "lagunitas" (Spanish for "littl ...

Samuel P
Samuel ''Šəmūʾēl'', Tiberian: ''Šămūʾēl''; ar, شموئيل or صموئيل '; el, Σαμουήλ ''Samouḗl''; la, Samūēl is a figure who, in the narratives of the Hebrew Bible, plays a key role in the transition from the biblical judges to the United Kingdom of Israel under Saul, and again in the monarchy's transition from Saul to David. He is venerated as a prophet in Judaism, Christianity, and Islam. In addition to his role in the Hebrew scriptures, Samuel is mentioned in Jewish rabbinical literature, in the Christian New Testament, and in the second chapter of the Quran (although Islamic texts do not mention him by name).

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir (water)
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Nicasio Reservoir
Nicasio Reservoir is a shallow, artificial reservoir in the Nicasio Valley region of Marin County, California, United States. It covers and sits in a drainage basin. It was created by the construction of Seeger Dam on the Nicasio Creek in 1961. Seeger Dam is a tall, long earthen dam owned by the Marin Municipal Water District. Controversy The construction in the dam aroused much controversy among longtime residents of the area. The Water District forced the displacement of many farms, including the McIsaac family farm and the Tomasini Ranch, on which the majority of the reservoir sits. The controversy stems from the fact the water from the reservoir is rarely used by the Water District, that the broad and shallow nature of the reservoir leads to quick evaporation, and that the dam has blocked valuable spawning areas for endangered coho salmon and threatened steelhead trout. Construction of Seeger Dam wiped out the salmon population in Nicasio Creek. The District briefly at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Inkwells (Marin County)
The Inkwells (also known as The Ink Wells) are 2 deep natural swimming pools in Lagunitas Creek, in Marin County, California. The upper Inkwell is also known as "Shafters", named after the former railroad bridge that bore its name nearby, whereas the lower Inkwell is simply known as "Inkwell" or "Hole" because it is deeper and darker. Together, they are known as "The Inkwells". They are a common swimming spot in summer, despite failing to meet current water quality standards due to high levels of coliform. The Inkwells are accessible by car as well as public transit, with a Marin Transit bus stop being less than a mile away. The Inkwells Bridge, which runs above the inkwells, is part of the Bay Area Ridge Trail. It also carries pipes that bring water from nearby Kent Lake and the nearby Nicasio Reservoir Nicasio Reservoir is a shallow, artificial reservoir in the Nicasio Valley region of Marin County, California, United States.

Bon Tempe Lake
Bon Tempe Lake is a reservoir in Marin County, California, managed by the Marin Municipal Water District. It is the widest lake in the Mount Tamalpais watershed, and on Lagunitas Creek. Beneath its dam is Alpine Lake. Lake Lagunitas is immediately to its east. Built in 1948, with the construction of the earthen Bon Tempe Dam, the lake's name is an Americanization of the Bautunpi family name. The Bautunpi brothers ran a ranch and dairy that was removed with the creation of Bon Tempe and Alpine reservoirs. Fishing and hiking are activities around the lake. Rainbow trout and both largemouth and smallmouth bass are caught in the lake. The California Office of Environmental Health Hazard Assessment released warningregarding eating fish caught from this lake based on the elevated mercury level.
