Thornton's fishing scene is built around stillwater — specifically a handful of urban lakes tucked into the city's park system that punch above their weight for a metro area. Thornton Gravel Lake #2, Lake Erie, and East Lake Number 2 are the three main spots, all lake fisheries where you're casting from the bank or a small watercraft rather than wading a river. These are accessible, low-barrier waters that work well for anglers who want a few hours on the water without a long drive into the mountains. The tradeoff is that you're fishing managed urban lakes, not wild backcountry water, so expectations should be set accordingly — these spots reward patience and local knowledge over technical fly-fishing skill. Colorado Parks and Wildlife periodically stocks urban lakes along the Front Range, so timing a visit around a recent stocking can make a real difference in your success. A valid Colorado fishing license is required for anyone 16 and older at all three locations. If you're new to fishing or introducing kids to the sport, these lakes are a reasonable starting point — flat ground, easy access, and no technical water-reading required.
The activity listings cover lake fishing at Thornton Gravel Lake #2, Lake Erie, and East Lake Number 2, but the specific species present aren't detailed in available data. Front Range urban lakes in Colorado are commonly stocked with rainbow trout in cooler months and may hold warm-water species like bass, bluegill, or catfish year-round. Check the Colorado Parks and Wildlife stocking report online before your trip — it's updated regularly and will tell you exactly what's been put in and when.
Yes. A valid Colorado fishing license is required for anyone 16 years of age or older. You can purchase one online through Colorado Parks and Wildlife or at local sporting goods retailers. Day licenses are available if you're not a frequent angler.

A medium-light spinning rod in the 6- to 7-foot range covers most situations on these urban lakes. For stocked trout, PowerBait, small spinners, and worms are reliable producers from the bank. If you're targeting warm-water species, bring a few soft plastics or small jigs. There's no need for specialized equipment — this is straightforward bank fishing.
Early morning and the hour or two before sunset are generally the most productive windows at stillwater lakes, when fish are more active near the surface and shoreline. Midday in summer can slow things down significantly as water temperatures rise. In cooler months, midday fishing can actually be productive once the water warms slightly from overnight lows.
Yes, all three locations are urban lake fisheries with bank access, which makes them approachable for beginners and families. You don't need to read moving water or navigate difficult terrain. Bring a simple setup, check recent stocking reports so you're fishing water that's been recently loaded, and plan for a morning session when fish tend to be most active.
