The John Martin Reservoir Fishing Derby in Penrose, Colorado, transforms a quiet stretch of water into a lively stage of competition and camaraderie each season. Situated along the Arkansas River’s expansive embrace, the reservoir invites anglers of all skill levels to engage with a water body that’s fiercely alive, its currents pushing forward with quiet energy. The derby itself is more than a contest; it’s a chance to measure wits against the reservoir’s swirl of trout and bass under the vast Colorado sky.

Entry begins at dawn, when the air is sharp and the water reflects the morning light like a restless mirror daring you to make the first cast. Spanning roughly 15,200 acres, John Martin Reservoir offers variety in fishing spots—open water surrounded by wide plains, along riprap dams, or near river channels where fish congregate, each area shaped by the natural pulse of water and wind.

Terrain around the reservoir ranges from gently rolling grasslands to rocky, exposed banks, demanding sturdy footwear that can handle loose gravel and occasional muddy patches near the shoreline. Elevation here sits at about 3,900 feet, which lightens the demands of altitude but still encourages pacing and hydration discipline—water carries the risk of deceptively quick sun exposure.

Planning for this event means arriving with more than just your gear—it’s essential to pack layered clothing for sudden weather changes, sunscreen to respect the sun’s persistence, and a reliable cooler to keep your catch fresh. Fishing licenses are required, so secure your permit beforehand to avoid any fines. Consider the timing of the derby; wind often picks up in the afternoon, making casting a challenge, so early starts offer calmer, more promising waters.

The John Martin Reservoir is fiercely itself, an ecosystem both generous and challenging. Its currents and close-to-shore weeds offer hiding places for fish but also teach patience and skill. For families and serious anglers alike, the derby offers a structured yet wild encounter with nature.

Beyond fishing, the surrounding lands reward visitors with sweeping views at lookout points and occasional wildlife sightings—deer browse near the water’s edge, while great blue herons stalk the shallows with deliberate grace. Though the derby’s heart is competition, its life pulses with opportunities to engage with this segment of Colorado’s high plains in a way that’s direct and effective.

Whether you're casting for your first trout or chasing a personal best bass, the John Martin Reservoir Fishing Derby stands as a practical adventure. You’ll come prepared, land a prize or two, and leave with a vivid sense of a water body that delivers challenges without excess fuss, riding the natural rhythm of the land and wind under a wide-open sky.
