New Braunfels Utilities is preparing for tighter water restrictions as the temperatures rise and the aquifer level falls. The utility, which has been in Stage 1 since October, said that rising temps, lack of rainfall and increased water use means the level of the Edwards Aquifer is dropping. On Friday, the 10-day average for the well that measures the aquifer's level was about five feet above the trigger that would push the city into the second stage of restrictions. If Mother Nature doesn't change course, officials said those restrictions could go into effect within the next few weeks. While under any water restrictions, the schedule for the use of a sprinkler or irrigation system is limited to one day a week by addresses, with addresses ending 0 or 1 having Monday, 2 or 3 having Tuesday, 4 or 5 having Wednesday, 6 or 7 having Thursday and 8 or 9 on Friday.
