Army Corps of Engineers officials say it has taken some negotiation with the different parties involved, but they are ready to release the plan for managing the flow of the Missouri River for this year. Corps spokesman Paul Johnston says the Fish and Wildlife Service had wanted the Corps to establish a flow rate in the spring and stay with it through the nesting season of some endangered birds. Johnston says the Corps will be able to move the nests if flood waters threaten the endangered birds, a technique he says actually increases the survival rate over what the birds would naturally have. In the meantime, Johnston says the Corps will release water from upstream dams to produce at least minimum navigation flows through the summer.
