Some are still working without being paid.

"It may slow down the process but they're choosing to do straight for and make sure they're keeping the water and electricity and not doing extra projects, so that's very reassuring," said Abbygale Phillips, from Yakima County.
Some projects are on hold, like work with endangered species.
Most of the money for irrigation and power comes from off-budget funding.
