one OF the great problems concern
ing the Colorado is that of silt. The
Boulder canyon dam as planned would
store the silt for over three centuries.
II all We're caught and held. and for
nearly a century before greatly i'm
pairing its water storage function. It
IS hoped before that time other devel-
opnents above will so regulate the
How that not all Of its storage ca
paclty will be i.eeded, but it will all
ways be desirable to control the
floods Of the region between Boulder
canyon and Glen canyon. and before
the capacity OF the Boulder canyon is
entirely destroyed the Glen canyon
regulator can be built to take its
place. It will then be fresh and emp
ty of silt and will last to as much
later date as the age of the Boulder
canyon reservoir at that time and
will, therefore solve the silt problem
for period OF two or three hundred
years further into the future than If
it is built first, and can. If desired, be
employed as a sluicing agency for
sluicing out the Boulder canyon res
ervoir.
IF built first. the Glen canyon res
ervoir would Immediately begin silt
ing up and IL sluiced in the future
Will discharge its sediment into the
reservoir later provided below and
thus require sluicing of the same sed-
iment two or more times. This null
tiple sluicing will not be possible
without shutting down the storage
and other functions of all the rescr-
voirs below while they are being
sluiced out.
BY the time silt deposits have be-
gun to encroach upon the storage ca
pacity OF the Boulder canyon reser-
voir sufficient power earnings will
have accrued to amortize its cost and
the full height Of the dam viii still
be available for the development of
power. The engineers OF that future
date will then not only be in a better
position to build the Glen canyon dam
than we are now, but will be relieved
Of the expense of a power dam at
Boulder canyon we would now be
saddled with and have in addition the
advantage OF being then free to oper-
ate the upper reservoir to best adj
vantage for power alone. the Boulder
canyon reservoir still affording ample
capacity for regulation for irrigation.
Recommendation
/. 1t is recommended that through
suitable legislation the United States
undertake the construction with Gov
ernment funds of a high line canal
from Lag1ina dam to the Imperial
valley to be reimbursed by the lands
benefited.
2. It is recommended that the pub
lie lands that can be reclaimed by
such works be reserved for settlement
by ex- service meil under conditions
securing actual settlement and culti-
walton.
8. Ii is recommended that through
suitable legislation the United States
undertake the construction with Gov
ernment funds of reservoir at or
near Boulder canyon on the lower
Colorado river to be reimbursed by
the revenues from leasing the power
privileges incident thereto.
T. IT is recommended that any
state interested in this development
shall have the right at its election to
contribute an equitable part OF the
cost or the construction OF the reser-
voir and receive for its contribution a
proportionate share OF power at cost
to be determined by the secretary OF
the interior.
s. 1t is recommended that the Sec
retary OF the interior be empowered
after full hearing of all concerned to
allow the various applicants their due
proportion of the power privileges
and to allocate the cost and benefits
Of a high line canal.
6. 1t is recommended that every
development hereafter authorized to
be undertaken on the Colorado river
by federal government or otherwise
be required in both construction and
Operation to give priority OF right and
use
list. To river regulation and flood
control
2nd. To use OF storage water for
irrigation.
9rd. To development of power.
