public Service company just last week, or at
least recently. ~en we will have several
other relocations reports involving the
Denver Water Board, irrigation ditches,
railroad companies, etc. ~ose will be
submitted very soon and probably all of
them will be submitted by June or July of
this year.

So much for reports. Now, although you
are probably aware of the description of the
project, perhaps I could give you a little
bit of a rundown on that so that you will

As you know, the darn itself is located
at the confluence of Plum Creek and the
South Platte River. That's about eight
miles south of Denver. The right abutment
will be in Douglas County and the left
abutment in Jefferson County. It will be
a rolled earth fill darn approximately 52

The top elevation is 5532. It will provide
a flood control storage of 215,000 acre-feet.

The spillway will be located on the left
abutment and it will be a concrete chute, 500
