Subdistrict No. 1

Water levels of the unconfined aquifer within Special Improvement District No. 1 (Subdistrict No. 1) were rapidly declining in the early 2000's and groundwater withdrawals were exceeding the total amount of recharge from natural sources and from diversions of the Rio Grande. This decline in the water table is a direct result of a prolonged drought and increased groundwater consumption. The decline in the water table will only worsen unless the total consumption of groundwater is reduced. 

Subdistrict No. 1 was recognized as a legal entity in 2006 and formed in order to take action to help restore a balance between available water supplies and current levels of water use, so that the San Luis Valley can continue to remain a sustainable agricultural community.
