Objectives <br /> The overall objective of this proposal is to provide hydrologic,suspended sediment,and nutrient <br /> monitoring at three sites in the Upper Sangamon River watershed.This monitoring data will provide data <br /> that will be used by the city of Decatur to develop a watershed management plan to protect the drinking <br /> water supply to the city and local communities and industry. <br /> Proiect Tasks <br /> To accomplish the project objectives,the following tasks will be undertaken. <br /> Task 1. Collect hydrologic,stage/discharge,data at monitoring stations. <br /> At all three stations,bi-weekly,a manual stage reading will be collected,as well as other site <br /> condition observations. Stream discharge rating curves that were developed by ISWS prior to 2008 for the <br /> Friends Creek bridge at Rt 48(ISWS#102)and Long Creek at Twin Bridge Rd.(ISWS#101)will be <br /> verified and updated with several manual discharge measurements made over a wide range of stages. <br /> Task 2. Collect suspended sediment and nutrient samples at monitoring stations. <br /> Bi-weekly suspended sediment,nitrate-N and total phosphorus samples will be collected by a <br /> field technician.Suspended sediment will be collected using a depth integrated method when conditions <br /> allow. Samples will be delivered and analyzed at the ISWS Public Service Laboratory in Champaign, <br /> Illinois. <br /> Task 3. Collect turbidity,pH,and temperature at monitoring stations. <br /> At all three stations,during each visit, in-situ turbidity,electrical conductivity and temperature <br /> data will be collected using equipment supplied by the City of Decatur. The City of Decatur will also <br /> supply all necessary calibration consumables. <br /> Deliverables <br /> The deliverables for this project are the data described in the above tasks.Hydrologic, suspended <br /> sediment,and nutrient data collected at each of the monitoring stations will be processed,computed,and <br /> compiled.Data will be maintained in a database at the ISWS and provided quarterly to the city of <br /> Decatur, IL and their designated consultant,Northwater Consulting. <br /> 4 <br />
