Fishing conditions

As many anglers have been discovering, the fishing is unexpectedly good at Horsetooth Reservoir right now. Fishermen have been overwhelmed by the trout fishing success. Few have not made their limit, and with good-sized fish. The rainbow trout are biting everything from worms, black spinners, and even rubber crawdads. It is well worth the drive for some great fishing. You do not need a boat! Right now the shoreline fishing is producing good fishing right now and both South Bay and Inlet Bay are open with plenty of parking. Satanka Cove is also a hot spot for trout right now.

Fishing regulations:

  • Walleye: Daily limit - 5 total (no size restriction)
  • Smallmouth and Largemouth bass: Daily limit - 5 total (size minimum is 12 inches; all bass in possession must be over 12 inches)
  • All species of trout in Horsetooth (rainbow, cut-bow, brown): Statewide limit of 4 total per day (no size restriction)
  • White bass, striped bass, or wipers: Statewide limit of 10 total per day (no size restriction)

Please refer to the regulation brochure printed by the Colorado Parks and Wildlife before you fish on any body of water. These regulations are for Horsetooth and the type of fish in Horsetooth. Other bodies of water around Horsetooth may have different species of fish and regulations specific to that body of water. It is your responsibility to know the regulations to every body of water you fish.
