There's no such thing as a nice position in the Springs. The Springs trumps "nice."
It'll be nothing like you're used to, that's for sure. What we call a "lake," you'd call a "puddle." Public lakes are crowded on weekends, and private lakes are expensive and scarce.
If she opts for the Springs, the closest "large" body of water will be Pueblo Reservoir (45 min. south). If she goes for Denver or Boulder, you will have more choices, but so will 1.2 million others.
With that said, I'd bring the boat AND find new hobbies.
