149 Near record flooding of several thousand acres with numerous unstilted homes flooded.
147 Several unstilted homes face flooding. All lake roads inundated at this point.
145 Preparations for major flooding should be rushed to completion as the lake roads are cut off by high water. A few unstilted cabins may suffer overflow.
144 Most camps across the lake begin to flood. Some homes will also face flooding especially homes that are not stilted. Preparations for flooding should be rushed to completion.
