ALERT: December 5th update on the status of the nationwide data transmission error preventing stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. As of 11/08/2018, The USGS has restored all impacted operational stream gauges to transmitting status. The status map of gauge outages from other agencies is here. The outage map will be updated each Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.

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.
143 Water begins to flow over Louisiana 164.
142.5 Expect some minor flooding of low area camps, however, all access roadways will remain open.
