Why are watersheds so closely monitored?
Watershed monitoring data can be used for many purposes, such as to determine source(s) of impairment, to provide input for management tools such as models, and to support scientifically-based decisions for preserving or improving the quality of a water resource (Figure 2).
How do we monitor watersheds?
USGS collects samples from streams across the Nation and analyzes for chemical, physical, and biological properties of water, sediment, and tissue. Data are collected for investigations that range from national in scale, such as the National Water-Quality Assessment Program (NAWQA), to studies in small watersheds.
What is included in a watershed?
A watershed is the area of land that drains into a body of water such as a river, lake, stream or bay. It is separated from other watersheds by high points in the area such as hills or slopes. It includes not only the waterway itself but also the entire land area that drains to it.

What is the difference between the Ohio watershed assessment and listing by use?
In general, listing by use allows more information to be transmitted and presents a more accurate picture of water quality in Ohio. Ohio continued to use a watershed-based listing approach, but shifted to a smaller watershed assessment unit size. Some of the large river units were split into smaller pieces.
What is the integrated water quality monitoring and Assessment Report?
The Integrated Water Quality Monitoring and Assessment Report (also called the Integrated Report) indicates the general condition of Ohio’s waters and identifies waters that are not meeting water quality goals.
Why is Lake Erie impaired for recreational use?
The western basin of Lake Erie has also been assessed for recreation use impacted by significant algae biomass present during the recreation season. As a result, Ohio is listing the shorelines and open water in the western basin as impaired for recreation use.
