feet wide and 900 feet long. Crest elevation
of the spillway will be 5500. The outlet
works is located near the left bank and this
is a rather unique outlet works because it
will have an intake weir that will control I
the conservation pool at elevation 5426 and
still allow the run of the river to pass
through the dam unregulated. This intake
weir at the front will have two low flow
gates, 4 feet by 4 feet, in order to allow
the river to go on thr.ough to supply whatever
water rights are needed downstream during the
time the conservation pool is filling up.
The maximum capacity through those low flow
gates is 1200 c.f.s.

The main conduit will be 13 feet in
diameter. It will have gates 5 foot 9 inches
by 13 feet to control the outlet to a maximum
design flow of 5000 c:f.s. The stilling basin
on the outlet works will be 35 feet wide and
100 feet long. The discharge channel eleva-
tion is designed at elevation 5375.

On this little brochure you will see
two pools given, one a little darker than the
other. The darker one is the area of the
conservation pool and that will cover 1150
surface acres. That's about a third larger
than the area of the cherry Creek Dam with
which you are familiar. The lighter colored
blue pool is the area of the flood control
pool, 5500. You will notice that it extends
up the South platte River to the vicinity
of the Kassler Water Treatment plant. For
that particular area up there we plan to
have dike protection around the plant so
that it can continue to operate and in order
to make. room for this dike, or levee, we will
have to construct a new channel a short dis-
tance to the east of it. That will allow the
waters to pass by the plant without damage to
it. We have been working closely with the
Denver Water Board on this problem and, of
course, they have a lot of other problems,
