Dupage County Watershed Analysis

Upon the signing of the Clean Water Act of 1965, President Lyndon B. Johnson said, “The banks of a river may belong to one man or one industry or one state, but the waters which flow between the banks should belong to all the people.” This statement is profound because it emphasizes the need of water is universal and should be accessible by everyone. But in order to preserve water organizations must be put in place that protect the water and make it accessible. In order to establish a global change in water sustainability, it is essential preservation efforts start on the local scale. The front runner in the local efforts to achieve sustainability is the protection of watersheds. The DuPage County has six primary watershed planning areas: …show more content…

In December 2002 the EPA Assistant Administrator for Water issued a strategy reminder entitled "Committing EPA’s Water Program to Advancing the Watershed Approach" This arrangement notice not just reaffirmed EPA's dedication to the watershed approach additionally reenergized endeavors to guarantee that EPA in general completely incorporates the watershed approach into program usage. The notice built up an EPA Watershed Management Council (WMC) to quicken endeavors to create and issue NPDES allows on a watershed premise. (NPDES, 5) Even though noteworthy water quality enhancements have been made amid the previous three decades, water quality issues remain. A large portion of the rest of the issues include complex blends of sources and effects that require coordinated, all-encompassing arrangements. As per the 2000 Clean Water Act segment 305(b) examination of the country's waters, “39 percent of surveyed waterways and streams, 51 percent of evaluated estuarine square miles, and 46 percent of evaluated lake, streams, and repository sections of land excluding the Great Lakes” (USEPA 2002c) , do not completely bolster water quality guidelines. That investigation recognizes point source discharges as one of a few driving wellsprings of weakness in surveyed lakes, waterways, and beach front assets (USEPA 2002d). Stipends given by the …show more content…

Basically, the premise is the model will simulate a hypothetical spill and model the river and downstream, of the spill. The program is called the Contaminant Model for Streams (CMS), it has been developed by the U.S Army Corps of Engineers and has been used to model similar events on small streams. In this model I will be evaluating the potential impact from a hypothetical spill from the development of an agricultural chemical reductions and storage facility. When I ran the CMS program I had to find hydraulic parameters which included stream width and depth. In order to make sure my data was accurate, I used information from the USGS website that asses the various levels of water in the East branch DuPage River from October 2015- November 2016. I wanted to create a model for the following: when the East Branch DuPage River was at its lowest level (low model), when the river was at its highest level perhaps due flooding (high model), and average water levels throughout the year (mean model). To accomplish this task, as stated earlier I has to find stream width and depth. In order to find these two I had to use two equations: Discharge= (Area)(velocity) and Area= (Depth)(Width). Given by the USGS website, the Average Discharge was equal to 51ft^3/s and the average velocity was equal to 0.09 ft^3/s. I plugged into my known variables
