Brownlee Reservoir is located between the western Idaho and eastern Oregon border, and is located at the uppermost part of Hells Canyon 20 miles from Cambridge Idaho. The southern part can be located at Oregon Farewell Bend State Park or Wesier Idaho Steck Park. The reservoir covers 15,000 acres of land, 58 miles long, and in some part more than 300 feet in depth level. There are three dams built on the Snake River to generate electricity for Idaho Brownlee dam, Oxbow dam, and Hells Canyon dam. The reservoir is the most heavily fished area in the state of Idaho, and produces a heavy amount of fish between the two states with the exception of the ocean. Some species of fish include flathead, catfish, crappie, bluegill, perch, bass, largemouth, trout, and rainbow.
With heavy amount of fish that are being produced from Brownlee Reservoir Idaho and Oregon monitors the fish and wildlife in the area. The department of Environmental Quality of Idaho and TerraGraphics Environmental Engineering conducted a study on rivers, connecting to the Snake River and Hells Canyon complex for any presents of mercury contamination. The study included rivers from Idaho such as Payette, Boise, Weiser, and Lower Salmon. Oregon Rivers include, Imnaha, Grande Ronde, Malheur, and Powder. Also included in the study were the Snake River below Brownlee Reservoir, and upstream from the Boise, plus samples were taken from Owyhee river. Scientist concluded that Imnaha River had the best results, because of its limited commercial area, very little industrial area, and no mines. Unfiltered samples were taken in June 2006 and the first week of September 2006. Special step were taken to gather the samples, so as to not contaminate the results. Gatherers wore contamin...

    The main problem was lead, with seven well samples showing up positive. The calcium and nitrates both had four samples showing up positive. Hydrocarbons had 3 samples showing a positive. Heavy metals have two positives,and bacteria had only 1 positive. Many men, women, and children are getting sick from horrible water pollution and some of the water pollutants cause cancer! So through all thirty of the tests we ran we got twenty one samples back that gave us a positive result. In conclusion the water in Hickory Hollow is justified, showing various

    INTRODUCTION: There are over 50 lakes and ponds in Cumberland County, Maine, all of various sizes and shapes. Many of these lakes serve different purposes, from hydrating plants to being a source of water for both animals and humans. With this responsibility, comes the question, are these ponds and lakes safe drinking water for animals and humans? Contaminated water poses a risk for both humans and animals.

It is 2334 km (1450 miles long), the longest river west of the Rocky Mountains. Its source is west of the Rocky Mountains which is the watershed in northern Colorado, and, for the first 1600km (1000miles) of its course, passes through a series of deep gorges and canyons that were created by the eroding force of its current. The river flows in a generally southwestern direction across Colorado into south eastern Utah, where it is joined by its chief tributary, The Green River. After crossing the northern portion of Arizona, the Colorado flows west for 436 km (271 miles) through the majestic Grand Canyon.

  • Oklahoma Fish Kill Study: Looking for a Toxic Needle in an Environmental Haystack

    1741 Words  | 4 Pages

    On July 9, 2011, a major fish kill (fish kill I) was observed by the Oklahoma Department of Environmental Quality (OKDEQ) in the Red River, near Ketchum’s Bluff, Oklahoma. The Red River, with headwaters in the Texas panhandle, flows for 917 kilometers, between the borders of Oklahoma (OK) and Texas (TX), before emptying into the Mississippi River. During this fish kill, hundreds of large bottom feeder fish (i.e., catfish and buffalo) were observed as either dead, struggling, or actively dying. Nearly two months later, on September 14, 2011, another fish kill (fish kill II) occurred further south along the Red River, approximately 130 km downstream from Ketchum’s Bluff near Lake Texhoma. Again, it was observed that hundreds of only the large bottom feeder fish were affected by an unknown toxin(s). OKDEQ believed that the two fish kills were related, with the unknown toxicant(s) traveling further downstream from the first fish kill (July 9, 2011), but causing fish mortality 60 days later downstream. The following year, on June 13, 2012, another fish kill (fish kill III) occurred, again near the area of Ketchum’s Bluff and Red Creek confluence. And a final fish kill (fish kill IV) occurred on January 31, 2013, in the same watershed, near Red River and Beaver Creek confluence. Environmental samples (i.e., water, sediment, and fish) were collected, by OKDEQ and the United States Envi...

  • The Colorado River Basin Drought

    1664 Words  | 4 Pages

    Americans today tend to believe that the Colorado River drought has been a recent occurrence, although drought relief strategies have been implemented since early 1997. To summarize, in the book The Colorado River Basin Drought Planning and Organizations, Colorado is named as the original state to acquire a drought relief plan. For instance, various assume water levels are diminutive in the Colorado and blame is due to the previous ten years of drought throughout the United States. Although it is true that water levels are at a record low, initial plans in the early 1920’s to introduce manufactured structures into the water basin is the original reason Colorado’s water system began to be compromised. It follows, then the supplementary natural

  • Gypsum Essay

    1228 Words  | 3 Pages

    Minerals are found worldwide and have countless uses. The mineral gypsum, is just one of the thousands named. Gypsum has always been a critical mineral in the building of innumerable ancient constructions, and is still being used in today’s construction. (The History of Gypsum, 1985) It is speculated that the first use of it was in ancient Greece, where is was called “gypsos”, or “selenite”, but, gypsum’s first recorded usability was in Ancient Egypt, where it was used in the building of the Pyramids. They used the material called “Alabaster” (which is a form of gypsum), but later in the 18th century, they realized that gypsum in its natural and raw state, was much too wet, so they altered it to create the building material called “Plaster

  • Sone Clay and Glass Industry

    994 Words  | 2 Pages

    Under the Stone, Clay, Glass, and Concrete is the Structural Clay industry which will be the primary focus of the report. Clay consists of the finest-grain particles in sediment, soil, or rock, and a rock or a deposit containing a large component of clay-size material. Clay can be composed of any inorganic materials, such as clay minerals, allophane, quartz, feldspar, zeolites, and iron hydroxides, that possess a sufficiently fine grain size. Along with organic matter, water, and air, clays are one of the four main components of soil. Physical properties of clay include plasticity when wet, the ability to form colloidal suspensions when dispersed in water, and the tendency to clump together (flocculate) and settle out in saline water. Establishments that fall within the Structural Clay Products Industry (SIC code 325) are primarily engaged in using different types of clay and other additives to manufacture brick and structural clay tile, ceramic wall and floor tile, clay firebrick and other heat-resisting products, and clay sewer pipe. The mining of clay used to make structural clay products are not included within SIC code 32.

  • Calcium History

    413 Words  | 1 Pages

    The product of CaCO3 is formed, “…from the reaction of carbon dioxide with burnt (I) or slaked lime (II)” (Kroker, Rohleder, Tegethoff). Historians and scientists have concluded that the natural element, calcium, was molded into different compounds due to the underwater pressure that collided with the volcanic rocks. In contrast, with high concentrations of carbon dioxide and low pressure, these calcium compounds can also be dissolved. The change in water pressure was due to drastic globate climate changes, and deformations of the seabed. This phenomenon can be hypothesized as the time when the Earth’s plates began shifting and colliding. As time progresses, vast limestone deposits on lakes and oceans (Kroker, Rohleder, Tegethoff). Calcium is not only known the main component for our teeth and bones, but aquatic life also depends on it (i.e. mussels and mollusks). Marble and chalk are also forms of calcium that undergo particular
