Request for Proposal
The DuPage River Salt Creek Workgroup (DRSCW) issued the RFP for Water Quality Monitoring on September 17, 2019. All proposals should be submitted to the DRSCW no later than 5:00 PM on October 11, 2019. Click to view and download the RFP for submittal deadlines and details.
The Lower DuPage River Watershed Coalition is putting the results of its comprehensive monitoring program to work. In addition to regulations imposed by Illinois EPA, the Coalition is voluntarily investing in a number of studies and projects to improve the health of the DuPage River and its tributaries.
The DRSCW submitted a Special Condition Report to Illinois EPA on March 31, 2018. The report fulfills certain annual reporting requirements related to participation in projects identified by the Lower DuPage River Watershed Coalition and/or studies conducted in collaboration with the DRSCW.
Illinois EPA is implementing nutrient reduction requirements for our waterways. In collaboration with the DuPage River Salt Creek Workgroup (DRSCW), POTWs in the Coalition will help fund the development of a non-point source/wash-off study, nutrient trading framework, and Nutrient Implementation Plan (NIP).
Chloride Reduction Program
High chloride concentrations in streams is a stressor to aquatic life. One way to address chloride loadings in streams is to reduce its source – commonly used road salt. The Coalition hosts annual workshops to help snow clearing operations (municipal and private) learn about and implement Best Management Practices (BMPs) to reduce salt (chloride) use while maintaining traffic safety.
Integrated Prioritization System (IPS) Tool
In collaboration with the DuPage River Salt Creek Workgroup (DRSCW), the Coalition’s monitoring data will be integrated with the DRSCW’s to update and improve the IPS. The Tool will identify the current most limiting stressors to aquatic life, management actions needed to address the stressors, and will indicate the likelihood that those management actions will restore impaired waters or (at least) result in incremental improvements towards that objective.
Hammel Woods Dam Modification
The Coalition identified this project as a means to resolve low dissolved oxygen levels, reduce nuisance algae, and eliminate a barrier to fish passage. In addition, some in-stream improvements will be included with the dam modification. The Forest Preserve District of Will County owns the dam and approved this project for both its safety and ecological benefits. The Coalition helped fund the initial assessment and engineering plans for the project. Plans for the final design are underway.
River Restoration Project (South of 119th St.)
This project is yet to be determined. The Coalition will use IPS Tool outputs to develop the project.
