Implementation Plan for the Bay Creek Lake Watershed
78 ac, so total application costs for the lake would likely range from $22,620 to
$56,160. The surface area of Vienna Correctional Center Lake is approximately 75 ac,
so total application costs for the lake would likely range from $21,750 to $54,000.
Dredging is typically the most expensive management practice averaging $8,000/acre.
Although cost is high, the practice is 80 to 90 percent effective at nutrient removal and
will last for at least 50 years (Cortell 2002; Geney 2002).
18.104.22.168 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 Soil
Stabilization and Restoration Practice (SSRP), Wetlands Reserve Program (WRP), the
Conservation Reserve Program (CRP), National Resource Conservation Service
(NRCS), Conservation Cost-Share Program (CPP), Illinois EPA, and Illinois
Department of Agriculture (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 Bay Creek 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
