We built two habitat (probability) models with Skamania reach training data where White Sturgeon recruitment was consistent. Other sources claim white sturgeon as long as twenty feet, weighing nearly a ton. The model was developed as a tool to aid understanding of the physical factors affecting quality and quantity of spawning and rearing habitat used by the endangered white sturgeon (Acipenser … 2005). Sturgeons are found throughout the Northern Hemisphere, in both fresh water and salt water. Visit the ODFW's agency site. For example, foraging habitat is closely tied to the migratory patterns of their food sources. The white sturgeon is North America's largest fish. Although occasionally found in the ocean, they primarily reside in large rivers and their associated estuaries, including the Sacramento-San Joaquin system in California, the Fraser River (British Columbia), and the Columbia River and its tributaries (Washington and Oregon). Adult and subadult white sturgeon spend most of their lives in the San Francisco Estuary and the Delta. Spawning in regulated rivers has been associated with deep, fast and turbulent waters over cobbles and boulder substrate, often downstream of the tailraces of dams.

White sturgeon are commonly found in deep, soft bottomed areas of estuaries, where movements in the water column is dependent on salinity. These prehistoric fish may live well over 100 years, and may not mature until they are 25-years-old. Montana has less than 30 miles of white sturgeon habitat in the Kootenai River. They use these to feel and smell food, so putting some stinky bait on the bottom is the way to go when you're sturgeon fishing. Overwintering sites generally have fine substrates with deep, slower-flowing water. These impoundments resulted in a loss of 37% of the free flowing river habitat and isolated white sturgeons between dams. However, most species live primarily in saltwater or brackish water, and migrate to freshwater to spawn.

Unlike with green sturgeon, white sturgeon are not often observed in the ocean and few fish tagged in California have been recaptured in Oregon. Since 1990, the Kootenai Tribe of Idaho has propagated white sturgeon in captivity and thousands of juvenile sturgeon have been released into the Kootenai River in Idaho. They have also been frequently spotted opportunistically foraging and transiting in the St. George, Medomak, Damariscotta, Sheepscot, Saco, Deerfield, East, and Susquehanna rivers. They are often found in swallow areas of the water.
