2.0 CONSTRUCT RECHARGE STRUCTURES
2.1 RECHARGE STRUCTURE NORTHEAST OF DEL NORTE
A tract of land suitable for construction of a significant ground water recharge structure located
northeast of the Del Norte adjacent to the Rio Grande canal system has been obtained through
agreement with the State Land Boazd. A copy of the letter of authorization and correspondence
with State Land Board is included in Appendix A. The tract of land consists of a 345 acre area
lying southeast of Colorado State Highway No. 112 in Section 1, T. 40 N., R. 6 E., N.M.P.M.,
Rio Grande County. A map showing the location of the recharge structures and some of the
improvements is included as Figure 2-1.
Diversions from Rio Grande Canal Laterals No's. 5 and SA were reconstructed through
cooperation with the Rio Grande Canal Water Users Association. To facilitate spreading of
diverted water, two berms were constructed across an existing drainage between the canal
laterals. The locations of the diversions and berms are shown in Figure 2-1. Berms were
constructed in cooperation with San Luis Valley Irrigation District.
Since the location of the recharge structure is a relatively short distance from the river, the
structure satisfies the objective of constructing a recharge structure which was designed to
overcome many of the icing problems in canal laterals resulting from running recharge water
during the late fall and early winter.
A total of six ground water monitoring wells, consisting of two nests, were drilled near the
principal recharge areas by a U.S.D.I. Bureau of Reclamation drilling rig and crew.
