Currently, Entergy and Montgomery County Emergency Officials are working to strengthen the Lewis Creek Reservoir Dam near Willis on which weaknesses were found a few days ago posing the potential risk of dam breach. Latest reports from Montgomery County OEM state "the dam remains intact, there are no breaches and failure of the dam is NOT imminent. Workers made good progress yesterday and last night to mitigate the soil slides along the levee. Efforts continue in advance of expected heavy rains."
