With all of its reservoirs at low levels, Tarrant Regional Water District will implement stage one of its drought contingency plan on June 3. The district advised its wholesale customers, which include Fort Worth, Arlington, Mansfield and the Trinity River Authority to implement a maximum allowable watering schedule of two days per week and other water-saving measures. The district's overall system is estimated to be a 75 percent capacity headed into the dry summer season. Lake Bridgeport is the lowest, measuring 17.35 feet below full level, and Lake Arlington is the least lowest at just under one-foot low. Cedar Creek Lake is three and one-half feet low while the other reservoirs measure the following: Richland Chambers, almost six-feet low; Lake Benbrook, two and one-quarter feet low; Lake Worth,just over three feet low and Eagle Mountain Lake at almost four and one-half feet low. Two years ago, Cedar Creek Lake dropped to eight feet low by summer's end. In the Cedar Creek Lake area, the East Cedar Creek Fresh Water Supply District and the West Cedar Creek Municipal Water Districts have already ordered watering restrictions. ECCFWS prohibits watering of lawns before 6 p.m. or after 10 a.m. The schedule goes into effect June 15. WCCMUD prohibits watering of lawns before 8 p.m. and after 10 a.m. The schedule is ongoing. Customers of both Cedar Creek Lake water districts are restricted to specific watering days based on whether their addresses are even- or odd-numbered. Customers should refer to their water bills to determine on what days they are allowed to water or contact the companies for more information. Generally, water restrictions also prohibit washing paved surfaces such as driveways, allowing runoff or leaks to go unrepaired and washing of vehicles.
