GIS in water resources term project 2015

The purpose of this project is to show how the health of fishes can be impacted by high or low levels of dissolved oxygen in river systems. The oxygen concentrations will be compared with theoretical values to determine if the river system is clean or polluted. A polluted system or system that has sufficient nutrients including phosphorus has an explosion plant growth and when this plants die the bacteria feed on the organic matter, in the process consume an increased amount of DO. This why a clean water system is ideal for a healthy aquatic system (McLean, 2015).
