USE CAUTION ADVISORY
As of May 10, 2011, the Olmsted County Sheriff’s Office is advising all users of Lake Zumbro to be cautious while on the lake. Please, slow down as water depths have changed.
Lake Zumbro has changed since the flood in September 2010. Users will find that water depths and channels have changed. Specifically, there is now a large silt bar near Fisherman’s Inn. As of May 7, 2011 the water depth at the highest point of this silt bar was only 2.5 feet below the water’s surface. Users of the lake, especially water-skiers, need to familiarize themselves with the new water depths.
At this time, it is unknown how the water levels will rise and/or fall as the Oronoco Dam is no longer in use. Underwater hazards may also exist due to the power of the flood waters. Various debris can be lying just under the surface of the water that can cause damage or injuries to users of the lake.
The Olmsted County Sheriff’s Office highly encourages all users of Lake Zumbro to familiarize themselves with the new water depths. Slowing down and learning the new layout of the lake will allow everyone that enjoys the water a safe boating season.

Sandy Point Boat Landing Closure:
Due to the flooding last Fall's flooding, the boat landing at Sandy Point is closed. A large deposit of silt was left in front of the landing making the landing nearly un-accessible for launching or landing watercraft. For safety reasons, the decision to close the access was made by the Sheriff's Office and Olmsted County Parks. At this time, it is unknown when the access will be re-opened.
Tips for Safe Boating

- Watch the weather.
- Be aware of changing water levels and conditions that would expose logs, snags or cause floating debris.
- Be cautious when boating in the vicinity of the dam.
