Lower Arkansas Valley Water Conservancy board meeting recap

From The La Junta Tribune (Bette McFarren):

Grant money has been received to complete the North La Junta Project started last year. The levee, destined to complete the originally planned project by the Corps of Engineers connecting from the bridge to Al Rite Concrete’s dike will be completed, raised five feet and strengthened. The grant was for $80,000; with the same chip-ins as last year, La Junta would pay $10,000, Otero County $10,000 and the LAVWCD $10,000, making a budget of $110,000. Kenneth Muth, the contractor from last year’s project, estimates $62,000 to complete the levee, leaving about $50,000 for further treatment of the sedimentation problem on the west side of the bridge.

The water quality problem is being investigated with the lining of ponds and lateral ditches to improve the water quality of the water returning to the river. Irrigation by sprinklers and other modern innovations will be tested in farms on three different segments of land illustrating different configurations of farms in the valley: Pueblo County, upper end of Arkansas; Otero County, middle part of Arkansas; Bent County, lower part of the Arkansas. The Pond Lining 319 Grant theorizes that, by reducing the amount of groundwater seepage the water quality at the river will increase. The grant total is $654,550, project length: four years. It has been accepted by the Colorado Department of Health and Environment in the contracting phase. The soil health phase will consider one water long ditch, one water short ditch and one average water supply ditch.

Goble’s report studies John Martin Reservoir and the idea of extra storage in the lower part of the valley. John Martin is a key component of the 1948 Compact between Colorado and Kansas, administered by The Arkansas River Compact Administration, which has three representatives from each state, governor appointed. The reservoir serves 11 Colorado ditches and five Kansas ditches. In addition, it is used to augment groundwater pumping from Colorado Irrigation, municipal and recreational wells. Colorado Parks and Wildlife manages a permanent pool. Active storage at this time is 330,700 acre-feet.

From going almost dry in 2011, it has gone to almost full in 2016. The permanent pool since 1976 could only be helped by Colorado River water. In May of 2017, ARCA passed a resolution allowing water from the Highland Ditch to be stored in the permanent pool (one year agreement, potential for renewal). Colorado Parks and Wildlife needs approximately 2,000 AF to cover evaporation.

The new source is expected to yield around 2,800 AF. A proposal will be made to the State of Kansas for a new 40,000 AF storage account in JMR. Nine Colorado water users have expressed an interest in obtaining additional storage in JMR. They are four augmentation groups (Arkansas Groundwater Users Association, Catlin Augmentation Association, Colorado Water Protective & Development Association, Lower Arkansas Water Management Association), two municipalities (cities of La Junta and Lamar), two conservancy districts (LAVWCD and Southeastern Colorado Water Conservancy District), one electric company (Tri-State Generation & Transmission Company). The increase would also benefit Kansas, in reducing the chance of un-replaced return flows, less evaporation charged to Kansas accounts, possible modification to the operating plan to allow Kansas to use certain water to recharge the Ogallala Aquifer, and better water quality.
