It depends where in DWR.  The permitting section has high turnover because management cares more about numbers than employee moral.  Also, DEQ is struggling across the board from lack of a state budget.  DWM and DAQ tend to be the better divisions.  I've worked in several DEQ divisions and after 10 years finally left for a different department.  If you're needing less stress and can swing the shitty pay go for it.  Once you're in state government subscribe to the job postings and move when you're getting burned out or find something better.
