Drawn from a special stakeholder symposium held in September 1999 in Keystone, Colorado, this issue explores how we got to where we are today on the Colorado River; an era in which the traditional water development of the past has given way to a more collaborative approach that tries to protect the environment while stretching available water supplies. Specific topics addressed include the role of the Interior secretary in the basin, California’s 4.4 plan, water marketing and future challenges identified by participants.
