The efforts to hold back the floodwaters and patrol the levees in Northeast Louisiana ended after the major break at Cabin Teele. Water entered the Upper and Lower Tensas Basins eventually through six direct breaks in the levee on the left bank of the Mississippi River. This major crevasse was a result of the Mound Landing crevasse which had broken the levee on the opposite [right] bank of the Mississippi River on April 21. After flooding the Yazoo Basin in Mississippi, the rushing water from the Mound Landing break reentered the river at Vicksburg, promptly causing the levee directly across the river in Louisiana to crumble. The other breaks in the main levee line occurred in Tensas Parish at St. Joseph on May 1 and Winter Quarters on May 4. In Concordia Parish breaks were reported on May 1 at Bougere and Glascock. These breaks were augmented by three breaks in the Arkansas River levee, which resulted in the total inundation of the Tensas Basin with the exception of the three notable high areas rising out of the floodplain. Mildred Nolan of Oak Ridge in Morehouse Parish remembered the Oak Ridge church bells sounding one night at 2:00 . confirming reports that the water had entered the town. With light from kerosene lanterns, she watched the heroic effort made by the men of Oak Ridge to fill sacks of dirt and build up an embankment around the town in an attempt to hold back the rising water. They also sandbagged every culvert under the railroad tracks which prevented any water from entering the west side of town. The small levee constructed by local manpower withstood the water's pressure long enough to enable many residents to move out of their homes before it broke (Nolan 1981).
