5. The flow into EVERY recharge structure MUST De metered and equipped with a
contintous flow recorder unless the water rnrrrrrdsstorrer >n oorrjundton with the
division engineer determines adequate records maybe kept wNtaut such
equipment. ff the recharge struchrre is designed to discharge water via a suAace
outlet, such discharge must also tie metered and equipped with a continuous
flow recorder. Unless provided an exemption from either the water commissioner
or division engineer for thin requirement, the water commissioner MUST approve
the meter. recorder and instanation and the instanation must be completed
BEFORE U1e Dhrtsian of Water Resources win adcnowtedge arty recharge credit
to Ure structure.
6. All recharge ponds must have a staff gauge irrstaned such that the gauge
registers the lowest water level in the pond. The staff gauge must be readable
from a readily accessible location adjacent to the pond.
7. All recharge areas must be malntalned in such a way as to minimize
oonsumpthre use of the water by vegetation. No recharge area maybe used
for tJa plantlng of crops during 1M soma irrigatlon year that a is used as a
recharge sib without prior approval from the Water Commisslorer or
Dhrlslon Englnear.
8. The amount of water redrarged io the alluvial aquifer is to be determined by
rreeasuring the amount of water denvered m the recharge struchrre and
subiradirrg:
a. the amount of water discharged from the recharge structure.
b. the amount of water bet to evaporation (see item 9, below).
c. the amount of water lost to cwreumpfive use due to vegefatlon located
vvithln the recharge stnrcture, and
d. the amount of water reta(ned in the recharge structure that has not yet
percolated irdo the ground.
8. Net evaporetbe losses from the recharge structure must be subtracted from the
volume of water delhrered to the pond. Evaporative losses must be taken every
day the pond has a visible water level. If the pond does not have a stageauAace
area curve approved by the water commissioner, the maromum surface area of
the pond must be used to determine the evaporetNe krsses. Monthy loss factors
prorated for the number of days Ihs pond had a visible water level may be used
as may real time evaporetion data from NOAH or a local weather station. B the
pond is not inspected on a roudne basis through R-e month, no prorating of
monihty faders will be allowed.
f o. The amount of aaxetions to the target stream wiY be determined using the
amount of water recharged to the aluvial aquifer (as described In item 8, above)
and lagging the recharge using the Obver equation, USGS SDF contour maps or
other mefftodofogy approved in advance by the Division of Water Resaurcas.
11. Accounting must be peAormed on a daffy basis with reports sutxnitted monthly
within 30 days of the end of the rrrorrth for which the accounting is being made.
