These water releases will continue until the Twain Harte Lake level has been reduced by approximately ten feet in elevation. This will lower the lake level to a point below where the leak is occurring. Water officials estimate it will take two days to complete this process. During this time, local stream levels will be above normal summer flows but below normal winter storm flows. While no flooding is expected persons living along Twain Harte Creek and Sullivan Creek should avoid those water ways until further notice.
Twain Harte Lake will be closed until further notice. For general safety, the public is asked to avoid Twain Harte Lake and the surrounding area to give emergency personnel room to work.
