The company prospered, and by 1920 Arcadia Orchards was the largest privately owned Orchard Company in the world, encompassing over 20,000 acres. Eighteen miles of flumes were built to pump water from Loon and Deer Lakes twelve miles from the City center. The lakes, however, became dangerously low, and in 1922 the company was forced to close. The Orchard Warehouse building is currently owned by the City and leased to the Deer Park Fair and Rodeo Association. Since that time, Deer Park has remained a residential, farming and timber community.
Many tourists pass through en-route to the many lakes and snow skiing areas situated nearby.
The City hosts a holiday tree lighting celebration the first Monday following Thanksgiving to kick off the holiday season. There are horse drawn sleigh rides, a live nativity scene, holiday music entertainers, Art show, a visit from Santa, and treats for all. Santa's has a workshop just outside the City limits and is open December 15th through 24th. There is a Christmas tree cutting farm on the edge of the City for those that wish to cut their own tree or purchase a live tree. The average growing season is 180 days.
