As a retired veterinarian who had a small animal practice and then obtained a Masters of Public Health and transitioned to working for the Virginia Department of Public Health as their first state public health veterinarian and later became deputy state epidemiologist I feel qualified to strongly agree with fencing cattle from streams. Livestock in streams are bound to have a negative impact on humans, animals, other living organisms and the local stream environment in general. I support the state's plan to help farmers help the environment.
