Indiana State Park Alerts

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

Several DNR properties may experience high use. Some may reach parking capacity for day use on busy weekends, and close gates or only admit vehicles when others leave. For real-time information, follow Indiana State Parks on Twitter (@INDNRstateparks) or Facebook (@INdnrstateparksandreservoirs). You may also wish to follow your favorite property on Facebook.

Blue-green algae

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.
