the dim projector, you can see the trails left
by the boat in the algae on Cherry Creek res-
ervoir.

Up on Lake Estes (slide) on the Big
Thompson system, we see the lake with Fish
Creek coming in on the south side of the road.
A group'of culvert pipes are over here. Just
by looking,at tones of the water, you can see
it certainly has different sediment concentra-
tions. There is a different kind of water down
here where Fish Creek flows in this sQuthern
part of Lake Sstes. This is the major part of
Lake Estes where it carries the flow off the
Big Thompson system.

This is a rather poor photograph (slide).
It got burned out in development. But this is
a rather infalllOus lilke and it may be that you
would like to take a look at it. This is Cheraw
Lake with an outflow coming out here, but it's
despersal plume doesn't show up very well.
There are heavy growths of I don't know what,
growing along the north shore of Cheraw Lake.

Down 'in the Russell Lakes in Saguache
County we find heavy growths of plants. (slide)
You can see that these lakes are well down the
road of eutrophication or aging. In fact, their
life is going to be limited to a few hundred
years and maybe much less than that. From the
vegetation that is coming in on the lakes on
these photographs you can see that the life of
this lake isn't going to be much longer.

Up on Eleven Mile Canyon reservoir (slide)
we look at the problems of the large growths
of cattail and other rooted aquatics at the
south end. The South Platte comes in just off
the bottom of the photograph. There are other
turbidity problems that you see along the edge
of the lake. The water is flowing in apparent-
ly from this direction, probably just out of
thiS' hole as the lake is being drawn down.
