The Bode plotter is an electronic instrument resembling an oscilloscope, which produces a Bode diagram, or a graph, of a circuit's voltage gain or phase shift plotted against frequency in a feedback control system or a filter. An example of this is shown in Figure 10.
The Water Quality Act of 1965 required states to issue water quality standards for interstate waters, and authorized the newly created Federal Water Pollution Control Administration to set standards where states failed to do so. No mechanism for federal enforcement was established.
It also influences policy by publishing studies and reports. Individual members typically take announce positions and some make the environment one of their specialties. The EPA is the concern of over half the Congressional committees. Some seventy committees and subcommittees control water quality policy, for example.
Biological quality (fish, benthic invertebrates, aquatic flora) Hydromorphological quality such as river bank structure, river continuity or substrate of the river bed; Physical-chemical quality such as temperature, oxygenation and nutrient conditions; Chemical quality that refers to environmental quality standards for river basin specific ...
Water quality laws govern the protection of water resources for human health and the environment. Water quality laws are legal standards or requirements governing water quality, that is, the concentrations of water pollutants in some regulated volume of water.

This body is responsible for advising the DEQ on the "implementation of a comprehensive, long-term water quality monitoring program designed to measure the quality of Michigan's streams, rivers and lakes, and detect areas of the state that need additional water quality control efforts." [3]
The section requires states to identify water bodies that cannot meet water-quality standards without control of nonpoint sources. The states must then identify best management practices (BMPs) and measures for those impaired sources, along with an implementation plan. The EPA approves these plans, and if a state fails to develop a plan, the ...
