Green Peter Reservoir, a profound and expansive impoundment near Sweet, Oregon, serves as a significant coldwater fishery within the central Western Cascade foothills. Meticulously managed by the Oregon Department of Fish and Wildlife (ODFW), it is preeminently known for its exceptional kokanee salmon and robust rainbow trout populations.

The primary piscatorial pursuits are its prized kokanee salmon, offering consistent action with typically larger specimens, and reliably stocked rainbow trout, ensuring high catch rates. Incidental, federally protected bull trout and established smallmouth bass also contribute to the lake's diverse offerings. Angling techniques are expertly applied: precision trolling with specialized gear, often utilizing downriggers, is paramount for deep-dwelling kokanee; varied methods for rainbow trout include trolling, still-fishing, and spin-casting; and lures for bass around structures. Optimal angling spans year-round for kokanee, with trout excelling in spring and fall. Access is generally good via multiple public boat ramps, necessitating watercraft for comprehensive coverage. Regulations, meticulously managed by the ODFW, are dynamic; strict adherence to current directives concerning bag limits, size restrictions, and mandatory immediate release of bull trout is unequivocally paramount for legal compliance and sustainable resource management within this deep, scenic mountain fishery.
