The Riley Purgatory Bluff Creek Watershed District partnered with the City of Chanhassen to install live lake level sensors on four lakes: Lotus, Lucy, and Susan, and Minnewashta. The sensors on these lakes collect data every hour and upload the data to the online dashboard about every 4-8 hours. The public can now view lake level data from these four lakes through the online lake level dashboard ⬈!

Please note that water levels of other RPBCWD lakes are also monitored but data is collected by different equipment and not transmitted to the lake level dashboard.

Tips for using the dashboard: To make sure you're seeing the most recent data, click "Refresh Data." Also click on "Show All" then "Show Last 7 Days" if you're not seeing recent data. For the most detailed results, select only one lake at a time when viewing the dashboard.
