Community planners need a tool to help them incorporate local water quality into development plans and land use decisions. This is exactly why Illinois-Indiana Sea Grant’s sustainable community planning team developed the Tipping Point Planner with Purdue University and partners. ESRI (Environmental Systems Research Institute) has highlighted the program with an article in their latest issue of ArcNews: With GIS, Communities See How Land-Use Changes May Affect Local Water Quality. Below is an excerpt:

Nutrient reduction in bodies of water is a critical goal for communities in the United States, particularly in northern states that border the Great Lakes, where nutrient loads—high concentrations of pollutants like nitrogen and phosphorus—threaten the health of rivers, tributaries, inland lakes, and bays. Communities often need to know the quality status of their watersheds and how development plans might affect that. Many questions arise during the planning process, such as the following:

  • Are current nutrient loads impairing surface water quality?
  • If we develop a particular site, would our streams or other bodies of surface water cross a critical threshold where they change from a healthy state to impaired?
  • What mitigation management strategies are the most cost-effective?

To answer these questions, communities need science-based tools that link planning decisions to water quality. These tools need to be established within a framework that involves community organizations, natural resource experts, scientists, extension specialists from land- and sea-grant universities, and concerned citizens.

Looking for a fun way to teach about marine debris? Check out Me and Debry, which is a whimsical, 30‑minute, audience‑participation play created for @UWiscSeaGrant. It helps students explore what marine debris is, why it matters, and how we can make a difference in the Great Lakes.The full script (English) and participation scripts (English, Spanish, and Hmong) are free to use, along with marketing materials for performances.Bring learning to life and start a conversation about litter in our waters!Check it out at the link in bio.#TeachingTuesday
Do you work or live along the Great Lakes coasts? Watch our newly released video series collection, containing several short videos that overview the range of coastal protection options in the Great Lakes, including:- Natural processes in the Great Lakes- Hard coastal protection structures and how they interact with/alter natural processes- Nature-based coastal solutions in the Great Lakes, ranging from green to gray approachesFind our two new video series at the link in bio.
Located in Washington, D.C., the Sea Grant Knauss Fellowship provides a unique educational and professional experience to graduate students who have an interest in ocean, coastal and Great Lakes resources, and in the national policy decisions affecting those resources. This is a one-year fellowship open to any student, regardless of citizenship, who is enrolled toward a degree in a graduate or professional program on the day of the deadline.Students enrolled at an Illinois or Indiana university or college should submit their applications through Illinois-Indiana Sea Grant by emailing Angela Archer at amcbride@purdue.edu. Students in surrounding states without a Sea Grant program should contact the National Sea Grant College Program at oar.sg.fellows@noaa.gov for a referral. Application deadline: June 3, 2026.To learn more about the fellowship, visit the link in bio.
