Another look at Eleven Mile shows it this time not in infrared, but in Echtachrome color (slide). We can see the orange color. This shows the patch that we saw before. It shows the South Platte coming in on Eleven Mile and I the large crops of green vegetation that here have been stranded high and dry as Eleven Mile was pulled down as it was rather severely last summer. Up on Williams Fork reservoir you again see the bright pink color. . (slide) The next frame shows hay meadows over in here - appar- ently well irrigated and well fertilized hay meadows so that the runoff water is going down into the lake. We are getting a good inflow of nutrients into the reservoir, and we have devel- oped this big bloom, a floating bloom of blue- green algae in the reservoir. By the way, this was a fact about this reservoir that the Denver Board of Water Commissioners, who owns it, wasn't aware of until these photographs showed up. You probably also saw the evidence we came up with a couple of years ago regarding algal blooms on Granby reservoir. This (slide) is one of my favorite res- ervoirs because of its many unique and inter- esting characteristics, at least to a scien- tist. This reservoir is Dillon. This is the Blue River inflow into Dillon. It's a beauti- ful reservoir sitting up there where it is. It is probably one that we have to watch more closely than any others because it is high on the Denver water supply system. The area is developing rapidly. There are sewage plants within spitting distance of the lake. There is a motel sitting down right next to the lake, I and boating activities of many types on the lake. Some people are predicting a population in the Dillon area of as great as 60,000 to 100.000 wi thin the n~t de=de. And if that ., happens, these problems that we already see on Dillon - the rooted vegetation growing up -48-
