As the first light spills across Lake Gregory in the San Bernardino Mountains, trolling for breakfast becomes less about filling a cooler and more about savoring the peaceful start to the day. Boat fishing remains a popular way to experience Lake Gregory in the San Bernardino Mountains, with anglers using rented or privately launched boats to reach areas that are less accessible from shore. The lake is regularly stocked with rainbow trout during the cooler months, while warm-water species such as bass, bluegill, catfish, and crappie provide additional fishing opportunities throughout the year, making it a productive destination across multiple seasons.
