43 CFR § 423.35 - Animals.
(a) You must not bring pets or other animals into public buildings, public transportation vehicles, or sanitary facilities. This provision does not apply to properly trained animals assisting persons with disabilities, such as seeing-eye dogs.
(b) You must not abandon any animal on Reclamation facilities, lands, or waterbodies, or harass, endanger, or attempt to collect any animal except game you are attempting to take in the course of authorized hunting, fishing, or trapping.
(c) Any unauthorized, unclaimed, or unattended animal on Reclamation lands may be:
(1) Removed in accordance with Federal law, and applicable State and local laws; and
(2) Confined at a location designated by an authorized official, who may assess a reasonable impoundment fee that must be paid before the impounded animal is released to its owner.
(d) The following animals are prohibited and are subject to removal in accordance with Federal law, and applicable State and local laws:
(1) Captive wild or exotic animals (including, but not limited to, cougars, lions, bears, bobcats, wolves, and snakes), except as allowed by a permit issued under subpart D of this part 423; and
(2) Any pets or animals displaying vicious or aggressive behavior or posing a threat to public safety or deemed a public nuisance.
(e) You must not bury, deposit, or scatter animal remains, or place memorials, markers, vases, or plaques on or in Reclamation facilities, lands, or waterbodies. This section does not apply to the burial of parts of fish or wildlife taken in legal hunting, fishing, or trapping.
(f) Where recreation facilities or other areas of Reclamation lands and waterbodies are operated through a contract or other agreement by a managing recreation partner of another Federal, State, local, or Tribal governmental entity, such as a State park, the laws, ordinances, and regulations of those partner agencies pertaining to animals and pets shall be enforced by those partner agencies. However, Reclamation retains the authority to take necessary actions to safeguard the security and safety of the public and such Reclamation facilities, lands, and waterbodies.
