Alexis Bonogofsky wrote about “reports of dead fish floating and collecting on the banks of the iconic Yellowstone River began coming into Montana Fish, Wildlife and Parks (FWP) in early August. The Yellowstone flows for 692 miles from Absaroka mountain range in Wyoming, through Yellowstone National Park, into the prairies of eastern Montana and finally, the Missouri River.
FWP officials took tissue samples from the dead fish to the US Fish and Wildlife Service Fish Health Center in nearby Bozeman, Montana. The whitefish were found to have died from Proliferative Kidney Disease (PKD), which is caused by a microscopic parasite known to occur in Canada, the United States and Europe. PKD kills fish by causing extreme inflammation in their kidneys and spleen. In the past 20 years, smaller and isolated outbreaks of the disease have occurred in two locations in Montana in addition to Washington,

In other words, it takes less energy to raise the temperature of the salt water 1°C than pure water. And in the winter time, adding salt to the ice lowers its freezing point, so even more energy has to be absorbed from the environment in order for it to melt.
AltonGas claims they monitor the river for dry weather conditions in Nova Scotia. In an article on their site they claim:
During the dry weather conditions in Nova Scotia in the summer of 2016, salinity levels in the river naturally exceeded 28 parts per thousand (ppt). When natural river salinity is greater than 28 ppt, brining operations at Alton are automatically stopped to protect the river. At this time, water will continue to be circulated in the cavern and brining activity will be temporarily suspended.
To check salinity levels in the river, there are salinity monitors upstream and downstream of the brine release point to constantly measure the river in real time. The monitors also control the brine release
Physical characteristics are important as well. While canoeing, many things were observed and notices. Tires were seen at the bottom of the river. This is most likely because of the highway that runs on both sides or the river, and over it -on bridges- too. Because of the highway, there is a high risk
The Neuse River, which means “peace” in the language of the Native Americans of the area, is located in the heart of North Carolina. The river has been flowing for over 2 million years and has helped provide energy and resources to the surrounding areas since before colonial times (North Carolina). Located just above Durham, NC where the Eno and Flat Rivers combine, the Neuse River is a vital part of a greater watershed area of central and southeast North Carolina.

On October 3, 2017 the 7th grade, team odyssey went on a trip to William Henry Harrison Park to observe the Portage River and the ecosystems around it. There the 7th grade team observed the the water quality of the Portage River. The 7th grade team used chemical, physical, and biological indicators to observe the quality of the Portage River.
Salinity is serious as it effects many things in the Murray-Darling Basin. If it continues to rise the consequences could be grave and quite long lasting, some
There are a number of environmental advantages that would occur upon decommissioning the Edwards Dam, most notably the rejuvenation of fish populations and the resulting increase in numbers of the osprey and bald eagles which feed upon them. Historically, the Kennebec River provided extensive top-quality breeding grounds for all ten species of anadromous fish native to the northeastern U.S., a distinction that the Kennebec River alone could boast of. Anadromous fish make their home in the ocean but embark upon the tough journey upstream once a year to lay their eggs. Since the erection of the Edwards Dam in 1837, and the subsequent construction of more than a hundred dams upstream of the Edwards, these fish have been effectively blocked off from prime spawning grounds. The removal of the dam would open up fifteen miles of these grounds, seventeen miles total before encountering the next obstruction, making this the longest uninterrupted stretch of high quality breeding grounds north of the Hudson River (Howe,1998).
Mackenzie River Basin has been steadily warming over the last 3 decades and changes due to global warming are rippling through the entire ecosystem. The indigenous communities that live in the basin and depend on the natural resources are particularly vulnerable to these changes. Some the changes that are detrimental to these communities include the increases in forest fires, increase of permafrost melting and the decrease of water in the basin. The increase
A recent study by Facebook states that “Facebook estimates that between 5.5% and 11.2% of accounts are fake. ”(TNW), and this is just facebook. Out of all social media sites and other account based websites people are masking their identities every day. Having the option to change a person's identity, is the scariest thing in the world to me, and it's even more scary because the internet is a vast abyss that can be manipulated into anything anybody wants it to be. Physically, identities are fixed, but digitally they aren't but the users creation, whether that be factual identities or not.
Although natural salinity contributions are somewhat unavoidable, manmade contributions can be fixed. Just being more mindful with the runoff we release could help a lot and maybe even also taking the step to use water treatments to improve the river’s water (Patrick 216).

The aim of this essay is to investigate the overall health of the Credit River located in Southern Ontario, Canada through data collected for phosphates, nitrates, dissolved oxygen and pH levels over many years. The Credit River originates around the city of Orangeville and then travels downstream for about 65 kilometers into Lake Ontario, near the Greater Toronto Area (Orphanos, 2004). It is essential to discover the health of this major river as it is one of the few which makes it way through the large urbanized zone including the city of Mississauga. There is a diverse wildlife that is supported by the water source, and it must be considered a priority to sustainably manage and investigate the concentrations of contaminants and water quality

Fishbowl Type of Strategy Indirect Grade Level(s) This strategy can be used with third through twelfth grade. Subject(s) This strategy can be used with all subjects, but it is more common in English classrooms.
Alberta Environment should complete a water management plan that identifies a science-based Ecosystem Base Flow (EBF) for the lower Athabasca River, as a low-flow threshold below which all water withdrawals would cease. The EBF should be legally enforceable and all water permits issued by the Alberta Government at any one time should be accountable to meet that EBF. In the interim, the low-flow threshold for the lower Athabasca River should be at least 100 m3/s.
The use of fish traps in the 1950s almost completely depleted salmon runs in some areas of Alaska. A fish trap is a big, fixed wooden structure, placed at the mouth of a stream to funnel to tons of fish into a massive net. Fish traps were also adapted to float so they could be a little bit easier to transfer in the winter. Fish traps needed little labor to keep them running, and they also kept the fish live which was important to the seller, which made them a good economic investment. The extensive use of the fish traps, and other fixed fishing gear heavily impacted the region and the Native people of Alaska.
