Izaak Walton Park- 18 South Sunset


In September 2013, Longmont experienced the most devastating flash flood event in its history. The flooding caused extensive damage throughout Longmont. Many of our parks and trails were impacted.

Several areas of Izaak Walton Park are OPEN. Izaak Walton Clubhouse is OPEN. The fishing pier is OPEN; however, the north, east and south sides of the fishing pond are CLOSED. The St. Vrain Greenway trail in this area is also CLOSED.

Please be sure to review the most up-to-date closure information due to flood damage and repair activities, found on the City's flood information website:


Izaak Walton Park was donated to City of Longmont in 1989 by the V.V. Golden Foundation. Used for nearly half a century by the Izaak Walton League for sport fishing and skeet-shooting, this facility sat unimproved until 1999. The new building is surrounded by park improvements including native vegetation, wildlife habitat enhancements and passive recreational activities. This District Park site is 21.5 acres in size which includes a 15.7 acre pond. The park is also a trail head along the St. Vrain Greenway. Gather Enough People Here is a mechanical art piece installed by Robert Tully in 1999, and is found at the southwestern corner of the pond. The pond was dedicated as a youth fishing pond.

Restrooms are available in the winter. Please keep your dog on a leash and pick up after your pet.

"Chick" Clark Kids' Fishing Program

kids fishing off bridgeThe 15.7 acre pond is managed as a recreational fishery for the exclusive use of children. Adults are encouraged to help kids fishing, but must help us preserve the fishing just for the kids. Naturally reproducing fish contained in the pond include:

The program stocks catchable rainbow trout in the spring and catchable channel catfish in the early summer. Kids may use live bait and keep the fish they catch up to the state limit set for each species. Open for fishing during the day only.

Fishing Hosts

The Kids' Fishing Program has a corps of adult volunteers who are available to help at the park. They are private citizens who generously volunteer their time to feed the fish, help kids with fishing techniques, and watch over the park during hours of operation. You can recognize them by their vests. Feel free to ask the Fishing Hosts questions or to seek assistance. Hosts will have the phone numbers needed for emergency services and for other information. If you are interested in becoming a Fishing Host, please call 303-651-8446 or email
