New Mexico Lower Rio Grande Regional Water Plan Demand - Future Use
A base assumption in development of the plan is that there will be no new water supplies and the current and future water resource is finite and limited
Major future changes in use within the region are anticipated to reflect a shift for municipal usage from full reliance on groundwater to significant reliance on surface water as populations expands
As there becomes a need to rely upon surface water, drought impacts will become a significant concern. Therefore, contingency planning for drought periods is necessary
