Boulder Reservoir is a popular 700-acre lake located just north of Boulder, Colorado. This expansive body of water offers excellent fishing opportunities with stunning views of the Front Range mountains. The reservoir serves as both a recreational destination and a water storage facility, providing approximately 20% of Boulder's drinking water. Situated on the plains but close enough to the mountains to offer scenic vistas, the Rez (as locals affectionately call it) provides anglers with diverse fishing experiences throughout the year, from open water fishing during warmer months to ice fishing when conditions permit in winter.

Colorado Stream Access Laws

With no clear test of navigability, no applicable statutes, and a tendency of courts to categorize all streams in Colorado as non-navigable, waterfront landowners' rights encompass the banks, beds, and waters of rivers. The public has no guaranteed recreation rights in non-navigable waters or their streambeds. CO Fishing Regulations: "It is illegal to go onto private land to fish without permission, including touching any part of private land by person or watercraft. Private land is not required to be posted or fenced. Trespassers may be suspended for up to 5 years."
