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.

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

Located near Cowan, Pennsylvania, Conley Run is a tributary of Buffalo Creek that has experienced severe degradation due to agricultural activity. Specifically, the deposition of large amounts of animal wastes, pesticides, and fertilizers has resulted in significant eutrophication throughout the stream. Furthermore, bank degradation associated with the movement of livestock has caused the displacement of foreign sediments into stream habitats. These factors, among many others, have caused the lake to be considered “impaired” by PA-DEP. In response, the Buffalo Creek Watershed Alliance, the the Union County Conservation District, and the Department of Environmental Protection and Fish and Boat Commision have partnered in an effort to restore stream habitat and create a riparian buffer to protect the stream.

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 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:

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

Background (1 ¶): What is the Duck Creek Watershed? What problems is it facing? What is being done so far to remedy these problems? Who is working on this problem?

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

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.

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

We live in an age where most environments on earth have been impacted by anthropogenic activities. For thousands of years, humans have been a natural component of ecosystems across the globe (Chapin et al, 2011). Human-environmental interaction contributes to processes that affect fluvial environments. For example, impervious surfaces are ubiquitous in urban areas; these anthropogenic surfaces reroute runoff (among other things), which can ultimately impact the morphology, water quality, vegetation, and floodplain soils of a local watershed, if it is near an urban area. Regardless of the anthropogenic presence throughout environments across the globe, ecological benchmarks can be set—physical, chemical, and biological—regarding what constitutes a healthy, natural environment. These parameters are important factors in ecological remediation activities and synonymous with the term “reference condition.” Based on a spectrum of watershed conditions—ranging from reference to

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.
