ProjectProject The Healthy Lake Huron: Clean Water, Clean
Beaches Initiative was created to reduce contamination along the southeast shores of Lake
Huron This project is to create a new Rural Stormwater
Management Model that will allow us to better understand and manage rural stormwater and limit
impact of runoff on water quality

ActivitiesActivities Develop specific software for a
rural stormwater management model Model base will be PCSWMM Agricultural best management
practices (BMPs) will be integrated into the software
![Page 21: Improved Understanding of Managing Stormwater in Rural Areas · 2015. 5. 26. · Improved Understanding of Managing Stormwater in Rural Areas A.D. Latornell – November 22, 2013](https://reader036.fdocuments.in/reader036/viewer/2022071107/5fe125aa731ba9610975634a/html5/thumbnails/21.jpg)
PCSWMM modified to incorporate:

Projected OutcomesProjected Outcomes Climate change adaptation Better understanding of rural flow
systems with application to rural flooding issues
Better understanding of BMP impacts More community / landowner
awareness of issues Tools to build more resilient
watersheds
