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 algae.IN.gov or the DNR's web page on blue-green algae.

    • MARINA FUELING: Due to issues with the fuel system, the Hardy Lake marina will no longer provide fuel for sale. Because there is no other fuel for sale on the lake, watercraft operators must be self-contained and/or bring their own fuel if needed. We apologize for the inconvenience.
    • RAPTOR CENTER: DNR will be permanently closing the raptor rehab portion of the Dwight Chamberlain Raptor Center at Hardy Lake, while providing a greater focus on educational programming at Hardy Lake and across the state. DNR is grateful for the Friends of Hardy Lake, and for the staff and volunteers who have assisted with both the rehab and educational programming since the center’s inception.
      The Dwight Chamberlain Raptor Center at Hardy Lake was established to introduce Hoosiers to live birds of prey and to offer a rehab facility where injured hawks, owls, and other raptors could be brought to be treated and, when possible, released. DNR stopped accepting birds for rehabilitation in spring 2022 due to an avian influenza outbreak. The impact of that outbreak has lessened, but there are still reports of this disease in the state. It is DNR's responsibility to protect the birds in the education program. Because avian flu is highly contagious, closing the rehabilitation side of the center reduces the potential of exposure for these educational ambassadors.
      With this change, DNR will devote more attention to training and enrichment for the education birds so their work of introducing Hoosiers to the habits and habitat of birds of prey is as effective as possible. Today, the number of licensed rehabilitators is greater than when the facility first opened. DNR’s Division of Fish and Wildlife maintains a list of these licensed rehabilitators that is available at on.IN.gov/wildliferehab.
