Based on your geographical location, it would be hard to rely only on solar heating during the coolest months of the year due to cool air temperature, low solar intensity, and likely cloud cover.
That being said, an appropriately sized solar system (roughly equal to the surface area of the pool) will certainly extend your swimming season during the spring and early fall seasons.
One good website for more information is www.powermat.com where you can find monthly temperature graphs showing what water temps you can expect for various geographical locations. (I couldn't find one for anywhere in Oregon, but there is one for San Francisco at www.powermat.com/sanf.HTML and one for Seattle, WA at http://www.powermat.com/seat.HTML)
Note to everyone: This is not a commercial recommendation and I don't want to imply that this site is the only source for information regarding solar heating (I don't work there or know anyone there). This is simply a site that I found that might have some of the information you're looking for.
Hope this helps ...

Irrelevant, solar power is completely useless
It is practical because alot of sunlight reaches Colorado, and solar energy is very abundant since the sun produces plenty of light to be converted to solar energy.
