, � � , <br /> changes, continued monitoring in the watershed is highly recommended. A sixth year of <br /> watershed monitoring at a reduced level is proposed to accomplish this. The addition of a sixth <br /> year of monitoring will enhance the baseline data already gathered thereby 1) developing a <br /> stronger base for attracting future funding for land management and mitigation programs ; <br /> throughout the watershed and 2) provide the background data needed to determine the progress II, <br /> of any future best management practices implemented in the watershed. The continuation of the �!, <br /> watershed monitoring has been recommended by several federal, state, and county agencies I, <br /> (USEPA, IEPA, county Soil & Water Conservation Districts (SWCD) and farm bureaus) as well ! <br /> as local watershed planning committees such as the Lake Decatur Watershed Planning Committee ' <br /> and Champaign County Soil& Water Conservation District Water Quality Committee. ', <br /> PROJECT OBJECTIVES <br /> The main goal of this project is to continue to assist the City of Decatur comply with the ; <br /> Letter of Commitment (LOC) agreed upon with the Illinois Environmental Protection Agency I <br /> (IEPA) by continuing to monitor the watershed for nitrates from May 1998 through April 1999. <br /> To accomplish this goal,we outline the following objectives. <br /> 1. Continue to maintain and operate the watershed monitoring network at a <br /> reduced level. Table 1 lists the present monitoring stations and the sampling schedule <br /> proposed. The Illinois State Water Survey will maintain the continuous stream recording <br /> equipment and the data records will be processed to determine continuous stream flows. Nitrate- <br /> N will continue to be sampled at all sites and visited weekly. This sampling schedule will <br /> provide the data needed to quantify the amount of nitrates being contributed to Lake Decatur <br /> from the watershed. <br /> Table 1.
