The time has come to talk about a little safety when you anchor your boat on the Columbia River and Willamette River.
With all the rain we have had, the Columbia River and Willamette River are high and there is a lot of stuff floating in the water.

White sturgeon spawns many times in their lives, as they age, the females spawn less often, but produce more eggs in each spawning. In the late spring or early summer, they congregate in areas of rivers with a heavy current, gravel bottom, and a water temperature of 58 °F to 66 °F (14 °C to 19 °C). The fish broadcast spawn in these areas, with males releasing sperm as the outnumbered females release anywhere from 100,000 to a million eggs. The fertilized eggs then sink and adhere to the gravel at the bottom. The eggs are brown in color and will hatch in about a week, depending on water temperature. Female white sturgeon does not spawn every year.
The Columbia River begins its 1,243-mile (2,000 km) journey in the southern Rocky Mountain Trench in British Columbia (BC). Columbia Lake, 2,690 feet (820 m) above sea level, and the adjoining Columbia Wetlands form the river’s headwaters. The trench is a broad, deep, and long glacial valley between the Canadian Rockies and the Columbia Mountains in BC. For its first 200 miles (320 km), the Columbia River flows northwest along the trench through Windermere Lake and the town of Invermere, a region known in BC as the Columbia Valley, then northwest to Golden and into Kinbasket Lake. Rounding the northern end of the Selkirk Mountains, the Columbia River turns sharply south through a region known as the Big Bend Country, passing through Revelstoke Lake and the Arrow Lakes. Revelstoke, the Big Bend, and the Columbia Valley combined are referred to in BC parlance as the Columbia Country. Below the Arrow Lakes, the Columbia passes the cities of Castlegar, located at the Columbia’s confluence with the Kootenay River, and Trail, two major centers of the West Kootenay region. The Pend Oreille River joins the Columbia about 2 miles (3 km) north of the U.S.–Canada border.
