Q1 and Q2 2024 Maps and Data Updates

We are very excited to share that several EGLE mappers were featured at the Improving Michigan's Access to Geographic Information Networks (IMAGIN)’s 31st Annual Conference. Zach Chamberlin and Emily Kirkpatrick from EGLE’s Water Resources Division received the “People’s Choice” award for their story map Shifting Sands: Michigan's Critical Dune Areas. Congratulations to Zach and Emily!

John Esch, who retired from EGLE earlier this year, was featured as the 2024 IMAGIN Geospatial Achievement Winner in recognition of his successes, leadership, and unwavering passion for advancing the field of geospatial and geologic technology in Michigan. If you’ve had the opportunity to cross paths with John, you know this is a very well-deserved award. Congratulations to John!

These protocols can be used to assess the existing condition of Michigan's wadeable streams and rivers as well as detect spatial and temporal trends. EGLE's Water Resources Division developed this map to illustrate their new Procedure 51 Site Classification system.
