⚠️ CRYSTAL LAKE – HARMFUL ALGAL BLOOM ALERT ⚠️
We have been notified that a harmful algal bloom has been identified in Crystal Lake in Crystal Township, Montcalm County, and warning signs are being posted around the lake.
For now, please use extra caution and avoid any areas where you can see green scum, streaks, discolored water, or other visible algae.
Please:
• Do not swim in areas where a bloom is present.
• Keep children and pets out of affected water.
• Do not allow pets to drink lake water where algae is visible.
• Avoid boating, jet skiing, or fishing directly through visible bloom areas.
Important: We have not yet received confirmation that the entire lake has been officially closed to all use. We are working to get additional information from the Mid-Michigan District Health Department regarding the extent of the bloom, test results, and any additional restrictions.
Algal blooms can move and change quickly depending on wind and weather conditions, so an area that looks clear at one point may look different later.
Please share this with your neighbors and anyone planning to use Crystal Lake. We will provide additional information as soon as we receive it.
When in doubt, keep out.
