record lows in the southern part of the basin

Depth to ground water is near historic record levels in

the southern part of the basin No precipitation is forecast in the near term

Streamflows are forecast to be below normal through

the next three months

La Nia conditions continue to strengthen, so drought is

likely to continue over the next several months
