"Chatfield" has gone through three stages:
Stage I, starting in geologic time, long ago, through 1975, when the dam was built and the reservoir
began to fill.
Stage II, from 1975 when water was impounded and the lake filled, until the recent disruptive engineering changes began, aka the "Reallocation Project". Those will be recalled as "the golden years" with much more habitat for birds than ever before.
Stage III, from completion of that project until some other project comes along.
When I moved to Denver in 1974 I strolled along the S Platte River upstream of the looming dam, through what would become the bottom of a big reservoir, dry shod, through dry farmland with a few buildings. No lake, no shore, scant habitat, not much, just the river.
I love Chatfield SP and the habitat that the dam and reservoir created, but try to keep in mind that BEFORE
there was a reservoir, there was a small river through dry land. Things change. I asked Thompson Marsh what
he thought about the dam and the reservoir, and he observed, "When people move to Colorado, they like to
have a drink of water and a flush toilet when they arrive." He recognized the reality of the situation.
My two cents,
