Missouri officials will be in Minnesota for the next two days, making their case against a change in management of the Missouri River.The Missouri River Basin Association meets in Minneapolis with the proposed management change the number one item of discussion. State Geologist Mimi Garstang says the state maintains its opposition to the so-called spring-rise proposal put forth by the Fish and Wildlife Service to protect endangered species. And Garstang admits there are times Missouri feels isolated in its fight. She says the proposed change could flood the state in the spring and cripple navigation. It also could leave the river level too low in the summer for public water supplies and utilities to draw from it.
