A Guide to Building and Managing Private Fish Ponds in Montana
The purpose of this handbook is to provide the prospective pond builder with an overview of the process of planning, permitting, constructing, and managing a successful private fish pond.

Registration of Koi or Goldfish Ponds
Koi and goldfish are controlled exotic fish species that can be legally kept indoors in an aquarium or outdoors in ponds that meet certain criteria. Such ponds must be registered with Montana Fish, Wildlife & Parks. For stocking of other fish species in ponds please contact your local FWP office.

Search for existing private pond licenses by name, business name, or license number.
No fishing license is required to fish on licensed, privately stocked fish ponds. Fishing license requirements apply to all other ponds and/or waters on private land.
