1 – Michigan needs a lot more dam investment. 

Since 2021, the state has invested $44.5 million in a Dam Risk Reduction Program. But it’s estimated that another $1 billion is needed to address dam infrastructure updates across Michigan. 

Recently, the state Department of Environment, Great Lakes and Energy, brought together state, local and tribal leaders in Traverse City to highlight what officials call an “urgent need for stronger action” to improve dam safety, enhance oversight and reduce risk to communities.   

Officials say recent flooding conditions are highlighting the importance of investing in dam safety. A House bill from Midland Republican Bill Schuette would expand oversight and funding for all of Michigan’s dams. 

There are more than 2,500 dams in the state. Many were constructed in the late 1800s and early 1900s. Around 1,000 dams are regulated by the state. Between 2022 and 2025, the Dam Risk Reduction Program funded 56 projects, including 20 dam removals, 16 rehabilitation efforts and 20 engineering studies.

2 – Macroinvertebrates like dragonfly and mayfly larvae are key indicators of stream health. 

Some species are highly sensitive to pollution. Others can thrive even in degraded conditions. 

By analyzing which species are present at sites, citizen scientists can get a clearer picture of the condition of a river. 

That’s why Little Forks Conservancy is seeking volunteers to sample Cedar River in Gladwin. A sampling event is set for Saturday, May 17.

This is the 12th year for the sampling program, which uses aquatic macroinvertebrates to help assess water quality in the river.

Six sites across Gladwin and Clare counties will be sampled during the volunteer event.
