The following may include road construction advisories, blue-green algae alerts, park and trail closures, and other notices. Check with the property office for the latest updates.

Blue-green algae is found in our lakes year-round. Under certain conditions, cells can reproduce in large numbers, and can result in a harmful algal bloom (HAB). We test many of our beaches where people use the water in the summer, but HABs may occur in other seasons, too. Watch for algae accumulation, avoid drinking or cooking with lake water, and do not allow children or pets to swim where algae accumulation is present. For more information, visit or the DNR's web page on blue-green algae.
