Ecological Integrity At Risk for the Cadron Creek Watershed in Arkansas

A separate tributary of Buffalo Creek, known as Stony Run, lies upstream from Conley Run. Since it is located in a dense wooded area with little to no agricultural interference, Stony Run has experienced very little degradation in comparison to Conley Run. However, Stony Run also shares a number of similar physical characteristics with Conley Run, such as discharge, watershed area, elevation and slope. Therefore, it will serve as a reference stream for this study.

Stormwater is water produced by rain or melting snow, which can rapidly flow over impervious surfaces into streams. Upland development magnifies the occurrence of stream bank erosion and in-stream nutrient pollution, which also have indirect negative effects. When stream bank erosion occurs, eroding sediment causes an increase in turbidity. Heavy stormwater flows into streams mixes the streambed sediment, which also increases turbidity, and ultimately causes declines in aquatic biota (Waters 1995). Therefore, negative externalities of upland development include

Extensive amounts of litter were observed both in (figure 8) and around the creek, this aspect of human interaction clearly is degrative within this environment Increased flood risk due to surface impermeability this disrupts the water cycle and increases subsequent erosion

The spatiotemporal pattern of water quality in the Reedy Fork and Buffalo Creek watersheds exhibits a trend of river deterioration, mainly due to Fecal Coliform. Our study suggests that most of the pollution sources were related to human activities. Looking at table 2a to 5b, it is clear that, F.Col, coliform is the dominant parameter with the highest means in all the sites, both at the Reedy Fork and Buffalo Creek watersheds. However, there are higher mean values of this nutrient in the Buffalo Creek watershed than the Reedy Fork creek watershed. This is clearly visible by looking at the variation in mean variable concentrations for the individual sites through the years under study from the graphs.

The objectives are habitat restoration, flood control, water quality, recreation development, and stewardship. The council has recommended to the City of Elk Grove the use of green infrastructure. This would allow for more of a natural drainage system that would preserve floodplains, wetland areas, and protects stream corridors. (Laguna Creek Watershed Council Work

This year I went on a field trip to the Conodoguinet Creek. This creek runs into the Susquehanna River and drains 500 square miles of diverse landscapes. Conodoguinet comes from an indian word meaning “a long way with many bends.” It begins near Carlisle at North Middleton Park and comes to an end in West Fairview, when it flows into the Susquehanna River. The Conodoguinet Creek is about 90 miles of bends and loops that meander throughout Cumberland Valley. When I went on this trip, I tested how fast the water was moving downstream. I also tested the creek for the acidity and eutrophication. Eutrophication is excessive richness of nutrients in a lake or other body of water, frequently due to fertilizer runoff from the

Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.

The goals for the West Saginaw Bay Watershed are based on the past studies conducted in the watershed. The goals are aimed at protecting the water quality and wildlife habitat and address the resource concerns of the watershed. Milestones were identified indicating the steps needed to reach the objective. Implementing most objectives requires a combination of three types of activities:

They filter out pollutants and excess nutrients, trap runoff and sediments, provide habitat for terrestrial and aquatic species, encourage biodiversity, act as wildlife corridors, regulate the temperature of the water, stabilize stream banks, and reduce the risk of flooding (Cunningham). However, such benefits cannot be yielded with buffers that are too small for the size of the stream they are protecting. To maximize the potential for a healthy river, 1st, 2nd, and 3rd order streams, or headwaters, must be thoroughly protected (Hawes). Thus, we have determined two minimum widths for riparian buffers in Andrews. 1st and 2nd order streams will have a minimum of 50 feet of riparian buffer because it is the legal North Carolina minimum (Kulz). A width of 100 feet was chosen for 3rd order streams and larger because this is the practice observed in Buncombe County, which is located in a similar geological landscape to Cherokee County, where Andrews is located. No development will be permitted within the minimum measurements for these riparian buffers.

One of the recurring problems at Howard County is the large quantities of stormwater runoff that flow into nearby streams. This is due to meteorological factors and physical characteristics including: land use changes. The more impervious surfaces there are the more surface runoff there will be; thus, placing adverse effects upon the environment. To be exact, these stormwater runoffs carry car oils, fertilizers, pet waste, litter, and sediment to the Chesapeake bay. Hence, 20% of the chesapeake bay’s pollution is due to stormwater runoff. However, not only does storm water contribute to pollution, but it also harms wildlife and its environment, as well as cause floods, erosion, and property damage. To address such issue, Howard Community College

This essay focuses on the way Hawthorne’s “Rappaccini’s Daughter” articulates the tension between the spirit and the empirical world. Hawthorne challenges the empirical world Rappaccini, both malevolent for his experimentation with human nature and sympathetic for his love for his daughter, represents, by raising an aesthetic question Rappaccini implicitly asks. Hawthorne never conclusively answers this question in his quest to preserve spiritual beauty in an empirical world, offering the most disturbing possibility of all: could art and the artist prove as fatal to the human spirit as empiricism?

The patterns of biological diversity in rivers and streams among taxa vary on a spatial and temporal scale (Ligeiro et al. 2010; McGarvey and Terra 2015). Variations in stream ecology can be contributed to water quality, habitat, and history of disturbance (Lingeiro et al. 2010). Creeks and streams feed into rivers and other larger bodies of water, which provide food, water, and other commercial and recreational services as well as a home to an array of plants and animals which rely on clean water. The health of these smaller bodies of water can act as indicators for the health of the larger watershed.
