9.5.2.8 Planning Level Cost Estimates for Implementation Measures
Cost estimates for different implementation measures are presented in Table 9-7. Cost
estimates shown in Table 9-7 are the total estimated cost per acre and many costs could
be reduced through cost share opportunities discussed in Section 9.5.1. The column
labeled Program or Sponsor lists the financial assistance program or sponsor available
for various BMPs. The programs and sponsors represented in the table are the SSRP,
WRP, the CRP, NRCS, CPP, Illinois EPA, and IDA. It should be noted that Illinois
EPA 319 Grants are applicable to all of these practices.

Total watershed costs will depend on the combination of BMPs selected to target non-point
sources within the watershed. Regular monitoring will support adaptive
management of implementation activities to most efficiently reach the TMDL goals.
9.6 Monitoring Plan
The purpose of the monitoring plan for the South Fork Sangamon River/Lake
Taylorville watershed is to assess the overall implementation of management actions
outlined in this section. This can be accomplished by conducting the following
monitoring programs:
Track implementation of management measures in the watershed
Estimate effectiveness of management measures
Further monitoring of point source discharges in the watershed
Continued ambient monitoring of all TMDL segments
Investigation of tile line flow and associated water quality from agricultural land
Continued documentation of tributary erosion
Further information gathering on area septic systems including locations and failure
rates
Storm-based monitoring of high flow events
Tributary monitoring
Tracking the implementation of management measures can be used to address the
following goals:
