Lake Information

Nestled within the picturesque landscapes of Grant County, Washington, lies Moses Lake, a captivating water body with a rich history and a crucial role in the region's irrigation infrastructure. With a sprawling expanse covering 6,803 acres, Moses Lake is not just a body of water; it's a vital component of the Columbia River basin, making it an integral part of the Pacific Northwest's natural heritage. Originally, Moses Lake was a shallow natural lake, but its destiny took a transformative turn in the early 20th century when it was dammed for irrigation purposes. This strategic move was a part of the ambitious Columbia Basin Project, overseen and managed by the United States Bureau of Reclamation. The project aimed to harness the region's water resources to support agriculture and facilitate sustainable land use. Moses Lake draws its lifeblood from Crab Creek, a meandering tributary of the mighty Columbia River. Additionally, it receives water from the runoff generated by the surrounding irrigated agricultural lands. While this lake once contributed its waters to Crab Creek, it now channels its flow into the expansive Potholes Reservoir, a reservoir that owes its existence to the O'Sullivan Dam, which adeptly impounds Crab Creek. For fishing enthusiasts and outdoor adventurers, Moses Lake is a haven waiting to be explored. Its waters are home to a variety of fish species, providing a thrilling angling experience. As you cast your line into the lake's depths, you might encounter species like Bass, Trout, and more, offering a rewarding challenge to both novice and seasoned anglers. Beyond fishing, Moses Lake offers a wealth of recreational opportunities. Boating, kayaking, and paddleboarding are just a few ways to savor the lake's pristine beauty and soak in the serenity of the surroundings. The lake's vast expanse invites you to embark on memorable adventures, from leisurely picnics on its shores to birdwatching escapades in the adjacent wetlands. In conclusion, Moses Lake stands as a testament to human ingenuity and the harmonious coexistence of nature and agriculture. Its transformation from a natural lake to a reservoir reflects the determination of the community to harness the land's potential while preserving the region's natural beauty. Today, Moses Lake continues to play a vital role in Grant County's landscape, offering not just irrigation but also a scenic retreat for those seeking solace in the embrace of Washington's great outdoors. It's a place where history, nature, and recreation converge, making it a must-visit destination in the heart of the Pacific Northwest.
