Preliminary numbers finding their way out of the Drawdown Regional Economic
Workgroup indicate that breaching Lower Snake dams could result in $158
million in direct costs to irrigators.
DREW has come up with estimated costs of various activities that would
be needed to implement drawdown or breaching of the four dams. Among those
activities are the costs to modify groundwater wells and pumping systems,
purchasing irrigated land, and establishing cattle watering corridors.
