26) Recharge pond accounting and operations must, at a minimum, include and/or comply
with the following information:
a) Measured and recorded inflow and measured precipitation as recorded by the
nearest CoAgMet weather station (Rocky Ford). Missing CoAgMet station data
must be replaced by the next closest CoAgMet weather station.
b) Daily content by staff gauge with a documented time recorded if not
automated.
c) Daily evaporation determined by daily evaporation rate by pond surface area
for each day water is present in the pond. Daily evaporation is determined
based on the pan evaporation at John Martin Reservoir as reported by the Corps
of Engineers from data collected. Alternatively, pond evaporation could be
determined using CoAgMet data from the Rocky Ford Station, applying a
shallow lake factor of 0.72 and using the equation 0.72"1.2"ETrs or 0.864"ETrs.
d) The recharge must be computed from a mass balance standpoint with no credit
for recharge of precipitation.
e) The area in and around the recharge pond must be kept clear of vegetation and
must be regularly monitored for any increased vegetative growth and/or pond
seepage coming to the surface. To the extent that any vegetation exists while
recharge is taking place, there must be an appropriate reduction applied to
recharge credits available at the Arkansas River.
27) Observations must be made and recorded of any spills, seeps, or overtopping of
recharge ponds when recharge ponds are near full. No credit for recharge infiltration
to groundwater shall be allowed when spills, seeps, or overtopping are observed unless
the amount of such spills, seeps, and overtopping may be estimated with reasonable
accuracy based on existing measurements and calculations and deducted from the
amount delivered to recharge as approved by the Division Engineer. Fields between the
recharge ponds and the river must be monitored periodically by Division Engineer staff
and Applicants to verify whether any elevated groundwater tables are induced by
recharge.
28) To the extent that the recharge ponds are used for purposes other than this IWSA, the
infiltration of such water to groundwater must be considered to occur based on the
percentage of the total delivery to the subject recharge pond. Recharge accounting
must be adjusted to reflect the proportion of water placed into recharge for IWSA
operations and for other purposes.
29) All diversions, deliveries for the Subject Shares, deliveries to recharge, and recharge
pond stage must be measured in a manner acceptable to the Division Engineer. The
Applicant must install and maintain measuring devices as required by the Division
Engineer for operation of this IWSA.
30) Applicant may exchange or store water in Pueblo Reservoir only so long as and to the
extent that they have a contract with the owners of that structure, and such storage
and use is within the effective time period of such contract. Applicant recognizes that
Pueblo Reservoir and Fountain Valley Conduit are owned by the United States Bureau
of Reclamation ("Reclamation"), and operated as part of the Fryingpan -Arkansas
