The final draft of Colorado’s Water Plan was submitted to Governor Hickenlooper in December. The plan is a compilation of Colorado’s abundant, complementary, and competing interests, all of which voice their concerns of how to best avoid the projected, mid-century gap. Over 13,000 comments were submitted to the Colorado Water Conservation Board and over 400 projects have been identified from the basin implementation plans.

Options on how best to achieve the goal of reducing the gap include: conservation, additional use of groundwater, recycling water, transfers of ag water to M&I, and additional transbasin/mountain diversions. All of the proposed strategies have their supporters and opponents. Through the use of analytical tools, can we determine the best, unbiased, and objective course of action for all Coloradans? The answer is, yes. This workshop will show how an open source and analytical model for the state water plan can aid policy makers in the identification and implementation of viable and efficient solutions to Colorado’s water problems.

It is the hope that interested water experts, from across the state, can participate with DARCA this year in a transparent and collaborative modeling effort for determining how to best act upon 21st century water problems. A modeling process is essential for discovery that may challenge settled beliefs, opening doors to previously unidentified solutions.
