ABSTRACT:Four ways of dealing with uncertainty in the resource planning process have been prescribed: to reduce it, to ignore it, to avoid it, and to convert it to risk as chance of occurrence for calculation in planning. This paper analyzes examples of water resource planning in the Connecticut River Basin to confirm, reject, or modify these prescriptions. The examples of planning chosen for analysis are navigation, flood control, and interbasin diversion for water supply. These confirm the desirability of reducing uncertainty, offer some support for strategies to avoid it and to convert it to risk, but do not support the desirability of ignoring it.
