All About Diamond Lake

Situated in the heart Washington’s Pend Oreille County, Diamond Lake is one of many sparkling bodies of water belonging to the Evergreen State. Centuries ago, sand and gravel dislodged from a glacier to form a natural dam, which in turn created the freshwater lake that exists today. Diamond lake is mostly spring fed, and drains into Moon Creek – which then carries the water to Sacheen Lake and the Little Spokane River.

Diamond lake’s exceptionally clear waters and warm summer weather attract visitors for a variety of activities like swimming, water skiing, jet skiing, tubing, fishing, and sailing. The lake usually freezes during the winter, creating conditions that are ripe for snowmobiling, ice skating, cross-country skiing and ice fishing. Camping is also extremely popular at Diamond Lake, with several nearby campgrounds to choose from. Hiking around the area yields astounding opportunities to view fantastic wildlife species, including minks and the occasional bear.

While Diamond Lake is small in size, at a mere 2.5 miles long and .5 miles wide, it is home to a surprising amount of fish. Anglers delight in the vast quantity of largemouth bass, catfish and yellow perch. Augmented by the Washington Department of Fish and Wildlife, Diamond Lake is one of the most heavily stocked bodies of water in the state of Washington – an average of 20,000 rainbow trout and 10,000 triploid and brown trout are transplanted yearly. A free public boat launch is locaed on the southeast side of the lake, also operated by the Washington Department of Fish and Wildlife.

Because all of Diamond Lake’s lots are privately owned, there are no public beaches; however, a large selection of lakeside real estate and luxurious vacation rentals are available – whether you are looking to relocate or to find a summer cabin rental. The local homeowners association, along with the Diamond Lake Improvement Association, provide guidelines and year-round activities for residents.

Several cultural attractions are situated near Diamond Lake, including the Tiger Historical Center and Museum and Newport’s Create Arts Center. Neaby, Metaline Falls’ Cutter Theatre, which served as the county school from 1912 to 1972, offers two historical libraries and a large theater. The Pend Oreille County Historical Society Museum is by far the premier locale to learn about the area’s rich past, particularly concerning the indigenous Kalispel tribe during the late 1800s.

For a day trip from Diamond Lake, don’t miss out on Riverside State Park. This massive 10,000 acre park is geared toward camping and fishing. Its rivers and freshwater marshes are ripe for swimming and boat exploration, and a myriad of picnic areas beckon to families looking to spend a day in the sunshine. North of Riverside, high in the Selkirt Mountains, sits the 13,919-acre Mount Spokane State Park. The highest point of elevation, at an impressive 5,883 feet, provides a stunning view of Canada on clear days.

Diamond Lake is less than an hour from the Spokane International Airport and 40 minutes from the city of Spokane – but somehow this convenient location does not compromise its isolated and organic ambiance. Whether you come for the phenomenal fishing, the sparkling waters or the gorgeous sunsets, Diamond Lake never fails to provide the ultimate lake getaway.
