From The Pueblo Chieftain (Chris Woodka):
The Lower Arkansas Valley Water Conservancy District has spent $1 million over the past three years to purchase the ditch from the Catlin Canal. It owns about 73 percent of the Larkspur. In November, the district filed for a change of use in Division 2 Water Court to allow for domestic and augmentation uses in addition to agriculture for the water. “It’s a transmountain water right, so it’s valuable because the water can be reused after it is brought over,” said Jay Winner, general manager of the Lower Ark district.
Larkspur Ditch brings 300-500 acre-feet of water annually from the Gunnison River basin into the Arkansas River basin through several collection ditches and a high-mountain ditch at Marshall Pass southwest of Salida. The Lower Ark district has improved the yield over the last seven years under a cooperative arrangement with the Catlin Canal Co.
Under a 1041 land-use agreement with the Otero County Commissioners, the Lower Ark has committed to offering first use of the water to users within the county. Initially, some of the water will be applied to Rule 10 group plans under the surface irrigation consumptive use rules approved in water court in 2010. The water is used to augment on-farm sprinkler systems. Several Otero County farms are enrolled in the Lower Ark’s augmentation plan.
