We will be using Sign Up Genius for monitor sign up. All members that swim at the pond are expected to monitor one time during the summer. The monitoring sessions will be split so that you can monitor half the time the pond is open and will be free to swim the other time. Watch for the details on this to come after the middle of April.

Gravel Pond Swimming

  1. Swimming will be allowed at three specific times:
    a. Monday from 4:30 pm to 7:00 pm
    b. Wednesday from 4:30 pm to 7:00 pm
    c. Saturday from 7:30 am to 10:00 am
  2. Staging and entry for swimming will utilize the designated beach area at the northwest corner of the Gravel Pond. Swimmers must remain to the west of the swim line buoys.
  3. Permittee must provide a designated person to act as a registration and safety contact on each date that the permittee intends to utilize. Members may not swim if the designated control person is not present. It may be possible for permitted groups to coordinate this with one individual acting as designee for all. The important factor is the control of access and the accumulation of user information.
  4. Permittee will track member access and egress at the Gravel Pond on a registration log sheet to ensure safety, provide management with accurate use information, and discourage unauthorized swimming by non permitted individuals or groups. The registration log sheet will record permittee name or organization, name of registration designee, date of use, name of swimming member, and member initials on egress.
  5. Permittee will submit copies of the registration log sheets on a monthly basis to the Chatfield Park Manager identifying members and each date of swimming participation at the Gravel Ponds.
  6. Failure of the permittee to provide accurate monthly reports and to report non permitted use may result in termination of the Special Use Permit.
  7. Permittee will encourage members to utilize the Kingfisher parking area on the north side of the main park road. Please remind your members that parking in non-designated areas or off roads is prohibited and violators will be fined and/or vehicles towed.
