Largemouth Bass
If you're chasing largemouth bass near Longmont, Colorado, your best bet is to focus on local reservoirs and ponds. Union Reservoir, just northeast of town, is a popular choice, but don't overlook smaller, lesser-known spots like McIntosh Lake or even some of the gravel pits that have filled with water over time. These smaller waters can hold surprisingly large fish with less fishing pressure. Spring and fall are prime times, as the bass move into shallower water to spawn or feed aggressively before winter. A key local tip: water levels in Union Reservoir can fluctuate dramatically, so check conditions before you go. Also, pay attention to the wind; a consistent breeze can concentrate baitfish and, consequently, the bass on the windward side of the lake. The largemouth in this region are known for being somewhat opportunistic, so a variety of lures and techniques can be effective, from crankbaits and spinnerbaits to jigs and soft plastics.
