The Range of Opportunities - Water Augmentation for the Colorado River System

From Study of Long-Term Augmentation Options for the Water Supply of the Colorado River System completed by the Colorado River Water Consultants (you can see the Water-Energy Nexus in all the alternatives - water augmentation will need energy and energy will need some form of water augmentation):

Alternative	Quantity Evaluated (Acre-feet per year)	Cost ($/Acre-feet)
Brackish Water Desalination	4,000 – 5,000	$700 - $2,000
Coalbed Methane Produced Water	3,000 – 20,000	$900 - $4,600
Conjunctive Use	8,000 – 40,000	$400 - $700
Ocean Water Desalination	20,000 – 100,000	$1,100 - $1,800
Power Plants – Reduce Consumptive Use	1,500 – 160,000	$1,000 - $4,000
Reservoir Evaporation	0 – 270,000	$500 - $2,000
River Basin Imports	30,000 – 700,000	Needs more refinement
Stormwater Storage	0 – 100,000	$600 +
Vegetation Management	20,000 – 150,000	$30 - $100
Water Imports Using Ocean Routes	10,000 – 300,000	$1,400 - $4,000
Water Reuse	20,000 – 800,000	$900 - $1,700
Weather Modification	150,000 – 1,400,000	$20 - $30
