The Conejos River PlanningModel (CRPM) was commissioned by the Conejos Water Conservancy
District (the CWCD) and completed in 1993. The CRPM was developed to support a change case in
the Division 3 Water Court allowing the use of Platoro Reservoir as an alternate point of diversion
for existing direct flow water rights. The model also could be used as a tool to allow the CWCD, the
ditches in the District and the Division Engineer to experiment with different operating schemes for
Platoro Reservoir to determine how the reservoir may best be utilized to benefit all water users in the
basin. The CRPM is operated on a variable time step ranging from 8 to 11 days over a study period
encompassing 1970 through 1990.
The Conejos River Planning model is an application of a proprietary modeling system developed by
Hydrosphere Resource Consultants, Inc. called the Central Resource Allocation Model (CRAM).
