Freshwater Drum


Freshwater Drum

Freshwater Drum are a non-native species in Colorado, first introduced in the 1950s as a sport fish and later accidentally stocked in some waters.

They're the only North American freshwater member of the drum family (Sciaenidae), which includes marine species like red drum and croakers.

Scientific Name: Aplodinotus grunniens


Physical Characteristics:
  • These deep-bodied, silvery fish are distinguished by their laterally compressed body, long notched dorsal fin, subterminal mouth, and unique lateral line that extends into the rounded tail fin.
  • Colorado's state record is just over 17 pounds, though they can grow much larger elsewhere, with the world record exceeding 50 pounds.

What to know

Habitat Distribution

  • They inhabit depths of 40-60 feet in medium to large lakes and reservoirs, preferring clear water but tolerating turbid conditions.

Key Locations

  • Reproducing populations exist in reservoirs including Jumbo, Jumbo Annex, Prewitt, North Sterling, Jackson, and Adobe Creek reservoirs, primarily in the South Platte and Arkansas River drainages.
  • Jackson Reservoir offers excellent opportunities for targeting drum along with carp, while Adobe Creek Reservoir has good populations accessible to both boat and shore anglers (though boat fishing is more productive).

Specific Spots

  • Focus on water depth using fish finders to locate schools, look for structure and drop-offs, find baitfish concentrations, and fish areas with strong current for larger specimens.
