Lake Gregory
Crestline, San Bernardino County, CA
Overview
Lake Gregory is a small mountain lake in Crestline, in the San Bernardino Mountains, at about 4,554 feet. It's the centerpiece of Lake Gregory Regional Park, managed by San Bernardino County Regional Parks and operated since 2021 by the Lake Gregory Community Recreation Company. The lake covers roughly 84 acres.
Can I bring my own boat?
Only non-powered craft. You can launch your own kayak, canoe or stand-up paddleboard (or another vessel lake staff approve) with a launch pass and a current-year Lake Gregory sticker. Gas motors are prohibited and private power boats aren't allowed. The motorized boats you'll see, such as Duffy boats and fishing boats with electric motors, are rentals.
History
The lake was built as a WPA project starting in 1937 on land called Houston Flat. Redlands grower Arthur Gregory, Sr. financed its completion, and the dam and Lake Drive across it were finished in January 1939.
Season
Non-powered boating and fishing are year-round. The swim beach and summer waterpark run from Memorial Day weekend to Labor Day weekend. The lake is stocked with trout in spring and fall.
