Colorado is currently developing its first Water Plan, a plan that will try and help solve the many water issues and future shortages we face. Some have said we don鈥檛 need one because we already have a 鈥減lan鈥� called Prior Appropriation. But the needs of 21st century Colorado are very different from those when 鈥淧rior鈥� became the foundation for water allocation across an arid landscape. In 1876 water was diverted to growing cities and farms with little care for the dry streambed that is the base value of Prior Appropriation.
Today we still need to manage rivers for the needs of farms and cities, but we are now also expected to provide for the needs of rivers, as rivers. Rivers are no longer just conduits for the conveyance of water. Biology and ecology are now as important as hydrology in the management of rivers. But natural river systems are filled with uncertain complexities. There is no Manning鈥檚 Equation for stream ecosystems.
Managing 21st century Rivers will also require an extended sense of ethics that includes rivers as rivers. If Colorado鈥檚 Water Plan is to truly provide for the stated value of 鈥渁 strong environment, with healthy rivers and watersheds鈥�, we need to create a plan that includes new ideas about engineering, science, law and ethics
