Langley — As we approach the July 4th holiday, both Grand and Hudson lakes, as well as the Illinois River, are open and ready to welcome visitors. Meanwhile, ahead of the holiday, the Grand River Dam Authority is reminding visitors to these waters to use common sense and take precautions if they plan to go swimming.

While swimming is always an “at your own risk” activity even during normal conditions, the recent elevated lake levels have generated some questions regarding water quality. However, the GRDA Ecosystems Management Department wants to remind the public that it continues to perform its water testing on a routine basis across both Grand and Hudson lakes and is not currently posting any type of swim advisories for the lakes. Also, the department does provide water quality data online at Just follow the “Water Quality Advisory Map” link under the “Environmental Stewardship” tab
