    The current environmental focus on controlling nonpoint pollution to protect our surface water has led to the discussion of management of riparian areas. The Environmental Protection Agency states that agriculture has a greater impact on stream and river contamination than any other nonpoint source. Grazing, particularly improper grazing of riparian areas can contribute to nonpoint source pollution. Negative impacts downstream include the contamination of drinking water supplies (55% of Ohios drinking water comes from surface water (Brown, 1994)), eutrophication of Lake Erie (Richards et al., 2002), and hypoxia in the Gulf of Mexico (Rabalais et al., 2001)...!!

    Possibly consider adding more details to this question. I think what your saying is "What is the negative effect of grazing cattle" on rivers? You can watch a very interesting documentary on where your food comes from, which should answer your question, and its called Food Inc. What you are talking about is NPS. Non Point Source pollution effects our country's fresh water supply. Its not talked about among Mass media and corporations as well as politicians.

    1.) Erosion (cattle eat all the plants which are needed to hold soil together)

    2.) water pollution (cow **** flows into the rivers through runoff and can cause diseases)
