• Where to Fish on Upper Lake

  We hold no survey for this water; read the slope of the shoreline instead. This is a lake, so the margins and the first drop matter most. Where the bottom changes texture, fish gather; find that line. Boulder County records list black-spotted cutthroat trout, brook trout, brown trout, bluegill and rainbow trout among the fish reported. County records show what lives in the area; the local agency holds the water-by-water list. Upper Lake repays a walk before the first cast.

• Seasonal Patterns

  Seasonal averages run from 17°F in January up to 53°F in July. Fishing here follows the temperature more than the calendar. Winter locks it down, and mid May brings it back.

Upper Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  The access position is unclear from public sources. The map shows no ramp or car park nearby, so this is a walk-in water. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Ask in the nearest town if you are unsure. Keep proof of licence with you rather than in the car. Should this one be busy, Stone Lake is 0.3 miles off. The position on Upper Lake is worth confirming on the day.
