Chatfield Reservoir is located 15 miles SSW of Denver in Littleton, CO.
There is a fee (seven dollars I think) to get into Chatfield state park. The park surrounds the reservoir. Access is very easy and there are a number of different access points and 2 different boat ramps. There is also a marina and a restaurant at Chatfield. Kayak and boat rentals are available.
The lake is bordered by wide open prairie grasslands with an expansive mountain background. This lake gets a good deal of boat traffic, especially on the weekends. The entire southwest portion of the lake does not get much boat traffic because much of this section of the lake is very shallow. The lake is just on the outskirts of the city yet it contains a fair amount of wildlife. I have seen many different bird species here as well as elk bathing in the lake, many deer, fox, prarie dogs, even a great horned owl hot on the heels of a rabbit one evening. The platte river leads into the southwest section of the reservoir and you can paddle upstream about half a mile before the current gets to strong to go against. Plum Creek feeds into the southeast side of the lake.
Warnings, Tips, & Other Details
Chatfield Reservoir is a good sized lake and if the winds are forecasted to be over 15 MPH then you probably don't want to be out there in a canoe or kayak.
