Lake Ballinger
Lake Ballinger is a freshwater lake with a surface area of 103 acres in southern Snohomish County, Washington. It is bordered by the cities of Mountlake Terrace to the east and Edmonds to the west. It is fed by Hall Creek at its north end and its outflow is McAleer Creek at its east end, going on to feed Lake Washington. The lake was formerly called McAleer Lake after logger Hugh McAleer, who was the previous owner of the lake and surrounding lands. It received its present name in 1901 when it was purchased by Richard A. Ballinger, future United States Secretary of the Interior, who named it after his father, Richard Ballinger."Ballinger Park Boat and Fishing Access" . City of Mountlake Terrace.

Puget Sound
Puget Sound ( ) is a sound of the Pacific Northwest, an inlet of the Pacific Ocean, and part of the Salish Sea. It is located along the northwestern coast of the U.S. state of Washington. It is a complex estuarine system of interconnected marine waterways and basins, with one major and two minor connections to the open Pacific Ocean via the Strait of Juan de Fuca—Admiralty Inlet being the major connection and Deception Pass and Swinomish Channel being the minor. Water flow through Deception Pass is approximately equal to 2% of the total tidal exchange between Puget Sound and the Strait of Juan de Fuca. Puget Sound extends approximately from Deception Pass in the north to Olympia in the south. Its average depth is and its maximum depth, off Jefferson Point between Indianola and Kingston, is . The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, is approximately . In 2009, the term Salish Sea was established by the United States Board o ...

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Goose Egg Addling
Goose egg addling is a wildlife management method of population control for Canada geese and other bird species. The process of addling involves temporarily removing fertilized eggs from the nest, testing for embryo development, terminating embryo development, and placing the egg back in the nest. Returning the egg to the nest misleads the goose into believing the egg is still developing. Otherwise, the goose would begin laying again. In order to work effectively, addling must be conducted in a manner that does not arouse the suspicion of the goose, and must not change the odor, appearance or texture of the egg. Effective addling techniques are disseminated by the Humane Society of the United States and Internet Center for Wildlife Damage Management. Perhaps the easiest way to addle is to coat the egg with corn oil, thereby depriving the embryo of oxygen and killing it. Canada geese are covered in the United States by the Migratory Bird Treaty Act of 1918.Migratory Bird Treaty Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecal Coliform
A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non-sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals. Fecal coliforms are capable of growth in the presence of bile salts or similar surface agents, are oxidase negative, and produce acid and gas from lactose within 48 hours at 44 ± 0.5°C.Doyle, M. P., and M. C. Erickson. 2006"Closing the door on the fecal coliform assay."'' Microbe'' 1:162-163. . The term "thermotolerant coliform" is more correct and is gaining acceptance over "fecal coliform". Coliform bacteria include genera that originate in feces (e.g. ''Escherichia'') as well as genera not of fecal origin (e.g. ''Enterobacter'', ''Klebsiella'', '' Citrobacter''). The assay is intended to be an indicator of fecal contamination; more specifically of '' E. coli'' which is an indicator microorganism for other pathogens that may be present in feces. Presence of fecal co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain , storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil Engineers Reston, VA [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alum
An alum () is a type of chemical compound, usually a hydrated double salt, double sulfate salt (chemistry), salt of aluminium with the general chemical formula, formula , where is a valence (chemistry), monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula . Other alums are named after the monovalent ion, such as sodium alum and ammonium alum. The name "alum" is also used, more generally, for salts with the same formula and structure, except that aluminium is replaced by another valence (chemistry), trivalent metal ion like chromium#Chromium(III), chromium, and/or sulfur is replaced by another chalcogen like selenium. The most common of these analogs is chrome alum . In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, , which is used for most industrial flocculation (the variable is an integer whose size depends on the amount of water absorbed into the alum).

Hypolimnetic Aeration
Via deep water aeration or hypolimnetic aeration, the oxygen demand of deep water is provided by oxygen from the atmosphere without destroying the lake’s natural stratification. Thus the deep water becomes aerobic, the dissolving of phosphates is reduced significantly and the production of ammonia by sediments improves. Scientific evidence shows that it is possible to keep the deep water clean through this process all year round via technical ventilation measures and thereby to recover the natural balance of lakes effectively.Steinberg, C., Bernhardt, H.: Handbuch Angewandte Limnologie – 14. Erg.Lfg. 4/0 Verlag: Hüthig Jehle Rehm, 2002, . Eutrophication In stratified, eutrophic lakes an oxygen deficit in deep water is created during summer stagnation. As a result of elevated nutrient inputs, the trophic level of many lakes increases continuously. Elevated phosphorus concentrations may lead to stronger algae growth and a corresponding increase in oxygen consumption in the d ...

Sedimentation Pond
A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture, aquaculture, and mining. Turbidity is an optical property of water caused by scattering of light by material suspended in that water. Although turbidity often varies directly with weight or volumetric measurements of settleable matter, correlation is complicated by variations in size, shape, refractive index, and specific gravity of suspended matter. Settling ponds may be ineffective at reducing turbidity caused by small particles with specific gravity low enough to be suspended by Brownian motion. Range of applications Settling basins are used as a separation mechanism to eliminate rejected products (i.e. waste solids management strategies) of a specified size and quantity in various fields, such as aquaculture, mining, dairy, f ...

Hypoxia (environmental)
Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure. In water, oxygen levels are much lower, approximately 7 ppm or 0.0007% in good quality water, and fluctuate locally depending on the presence of photosynthetic organisms and relative distance to the surface (if there is more oxygen in the air, it will diffuse across the partial pressure gradient). Atmospheric hypoxia Atmospheric hypoxia occurs naturally at high altitudes. Total atmospheric pressure decreases as altitude increases, causing a lower partial pressure of oxygen, which is defined as hypobaric hypoxia. Oxygen remains at 20.9% of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air (or blood) is decreased. This is common in the sealed burrows of some subterranean animals, such as blesmols. Atmospheric hypoxia is also the basis of altitude tra ...

Lake Forest Park, Washington
Lake Forest Park is a suburban city in King County, Washington, United States, located northeast of Seattle. It was developed in the 20th century as a bedroom community with single-family housing on medium to large-sized lots. Less than 4% of the city's land is zoned commercial, largely concentrated in one location, and there are no industrial areas. The city is situated at the northwest end of Lake Washington along State Route 522, which provides connections to Seattle and Bothell. Lake Forest Park includes several parks and nature reserves, access to the Burke–Gilman Trail, and organized summer events. The population of the city was 12,598 at the 2010 census. History Lake Forest Park was founded in 1912 by Ole Hanson as one of the Seattle area's first planned communities. Envisioned as a picturesque retreat for professionals, the developers planned roads and lots in strict consideration for natural landmarks. The original prospectus for lot sales declared: …the strict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
