IISG’s Lawn to Lake Program is focused on helping homeowners, landscapers, gardeners, and others adopt landscaping practices that reduce chemical runoff to local waterways, protecting and preserving those sources of water while maintaining thriving lawns and gardens.
There are a number of ways that everyone can keep local waterways clean while keeping their lawns green, and IISG has developed materials for homeowners, landscapers, and others to learn about how they can get involved.
“Don’t ‘P’ on your lawn” is a two-sided card (PDF) with healthy lawn tips and info on safe landscaping practices. The title is aimed at getting homeowners to watch out for phosphorus in their fertilizers, because phosphorus can lead to excessive algal blooms in waterways.

In late July, formal and non-formal educators joined @nature_indiana, @indianadnr Division of Nature Preserves, and @lakecountyparks for a workshop exploring ecological restoration in the Grand Calumet River Area of Concern.
Participants toured restored sites in East Chicago and Hammond, engaged with experts in sediment remediation and habitat restoration, and experienced a cutting-edge Virtual Reality curriculum aligned with NGSS for grades 6–12.
From industrial past to ecological renewal, educators left inspired and equipped to bring local environmental stories into their classrooms.
