• Determine the role of green infrastructure (GI) practices in reducing flooding by developing Long-Term Hydrologic Impact Assessment-Low Impact Development (L-THIA-LID) 2.2 models to simulate flooding (peak flow rate) and impacts of GI on reducing flooding
• Identify the long-term performance of GI practices in reducing flooding by improving the model algorithm to simulate GI practice efficiencies considering changes in performance of practices over time
• Enhance the optimization tool for selecting and placing GI practices to account for flooding
• Demonstrate the impacts of GI practice adoption on flooding through use of the improved model in analysis of potential and optimal GI impacts in the Washington Park community in Chicago
• Use the new tool to increase the understanding of impacts of GI practices in reducing flooding by providing outreach through tutorial and video instructional support including to community organizations around Chicago and classes at DePaul University and Purdue University

Story: Chicago and Milwaukee forecasters have a new tool to monitor potential flash flooding

• Develop and deliver an introductory fish health class for veterinarians and veterinary students, fisheries professionals and students, and other stakeholders in Illinois and Indiana

• Determine the factors that affect the survival of larval yellow perch in Lake Michigan
• Determine where young of the year yellow perch reside and are transported during the period between when the yolk is absorbed and when they are dispersed
• Document, based on thermal history in the otoliths and stable isotopes in the muscle whether life histories of alewife or benthic fish are closer to yellow perch thermal life histories
• Determine the impact of wind-driven movements of water masses on young of the year yellow perch distribution

This study aimed to estimate the total economic impact of recreational fishing in the Illinois waters of Lake Michigan, compare expenditure estimates from the creel survey with those from a mail and internet survey, and assess the economic impact of several fisheries within the Illinois and Indiana Lake Michigan fishery.

Little progress has been made toward reducing fatal drowning incidents in the United States (U.S.) in the last 20 years. Recent data from the Great Lakes indicate the COVID-19 pandemic resulted in excess drownings during summer 2020. Chicago has 26 miles of Lake Michigan shoreline and 24 free, public beaches that are punctuated with piers and jetties. The resultant structural currents pose unique risks to patrons who often access the lake outside of the official summer season and in the summer season after lifeguards go off duty at 7 p.m. There is an urgent need for effective education programs to raise awareness about recreation safety in Lake Michigan, the deadliest of the Great Lakes, and to increase water competence in diverse communities that have historically been excluded from swimming. The community-engaged injury prevention and water safety experts in Chicago are uniquely situated to respond.

Objective 1: To assess the impact of Chicago Park District’s Community Water Safety Trainings on program participant knowledge and skills, community-level knowledge, and distressed swimmer events and drownings.

Objective 2: To implement, pilot, and evaluate the Swim to Survive Program enhanced with Great Lakes safety education in Evanston, IL and adapt the program for implementation in Chicago communities.
