All Facts about 2007 Interim Guidelines for Colorado River Operations


The 2007 Interim Guidelines for Colorado River Operations provides temporary guidance on shortage management in the Colorado River Basin. Tiered shortage measures are triggered at Lake Mead Levels of 1075, 1050 and 1025 feet; if levels drop below 1000 feet the secretary of the interior must consult with the seven basin states to determine further measures [1]. The Interim guidelines outline requirements for coordinated reservoir operations, Lower Basin shortage guidelines, modification of the 2001 Interim Surplus Guidelines and creation and delivery of Intentionally Created Surplus (ICS) [2]. The ICS provision allows states to earn additional Colorado River water credits through four mechanisms: (1) Extraordinary Conservation ICS, (2) Tributary Conservation ICS, (3) System Efficiency ICS and (4) Imported ICS. Extraordinary Conservation ICS is generated by freeing mainstream Colorado water by fallowing agricultural land, lining canals or desalination. Tributary Conservation ICS is created by purchasing tributary waters within the contractor’s state that have pre-Boulder Canon Project Act water rights. System Efficiency ICS is generated by financing a project to reduce water loss; this credit is temporary and does not extend to the life of the project. Imported ICS is created by introducing water not naturally in the Colorado River watershed into the mainstream Colorado [3].
