Our main water supply is in better shape than it has been in more than a year. Lake Meredith, north of Amarillo, supplies Lubbock, and 10 other West Texas cities with water. About half comes from the lake and the rest from groundwater sources. The lake level is more than 53 feet. A graph from the U.S. Geological Survey shows the lake recovered almost as much in the past week as it did during early September. However - the ideal level for the lake is closer to its all-time high of 101.85 feet. The record low is 45 feet, and that came in July of this year.
