NORMAN — New water conservation measures are in place in Norman, where the dropping levels of Lake Thunderbird are threatening the city's water supply.
Beginning Monday, outside watering will be limited for residents. A local newspaper reports that even-numbered addresses can water outside on even-numbered calendar days, while odd-numbered addresses can water on odd-numbered days.
All outside watering is prohibited on Wednesdays and Thursdays.
The limitations are in place after the Center Oklahoma Master Conservancy District asked Norman, Del City and Midwest City to reduce their use of lake water by 10 percent because of drought conditions.
About two-thirds of Norman's city water supply comes from Lake Thunderbird.
The Central Oklahoma Master Conservancy District has warned that the drought that has lowered lake levels may extend another two or three years.
