Glenn D. Toyne - Well Augmentation Project

Introduction

Glenn 0_ Toyne (GOT) is applying for a $75,600 Small Project Loan from ttle Construction Fund to
construct a- system of wells and a recharge pond to replace out-of-priority irrigation well depletions.
The estimated total cost of the project is $115,000. Please see the attached project summary and
map.

Backaround

The Toyne farms, are located in Sedgwick County, approximately 14 miles Southwest of Julesburg,
Colorado, on bOth the south side and north side of the South Platte River. Together the family,
sons Glenn and Dave, and father L.D. Toyne, irrigate a total of 517 acres with 8 tributary
groundwater wells. The wells were drilled in the late 1960's and early 1970's. The wells pump on
average 1100 acre-feet of water annually. The water is typically used to irrigate corn, alfalfa;
beans, and wheat. The 8 wells are currently ~!Jgmented under the Groundwater Appropriators of
the South Platte (GASP) plan of operation. . :,

While GOT does have ties to ditch and reservoir water, they do not have any direct ties to
augmentation water for their 8 wells. This would be considered fairly typical when looking at .
irrigated farms in the lower end of the South Platte River. As such GOT is required to replace
depletions from well pumping when there is a senior water right "call" on the river. GDT has
succes~~I!y used GASP for the past 30 years to cover depletions on thes~~wells. GASP operates
on a year-ta-year basis with no guarantee of continued coverage. The current drought has brought
to the foreground the difficulty of providing augmentation for well users. The applicant states that
GASP has indicated that if the drought continues well pumping may be curtailed this summer.

GOT wants to develop a recharge system, similar to the ones developed by several neighbors,
including the State's Tamarack project, that will be used to offset the depletions caused by its 8
