Show 33 horseshoe- shaped course northward through Utah, Wyoming, and Idaho and then southward back through Idaho into Utah to the Great Salt Lake. The principal tributaries to the Bear River are Smith's Fork in Wyoming, the Malad River and Cub Rivers in Idaho, and the Logan River in Utah. The headwaters of the Weber River begin in the Wasatch Mountains, just south of the headwaters of the Bear River at the 10,500 foot elevation. The river flows in a northwest direction toward the Great Salt Lake. The Ogden River, which is the main tributary, joins the Weber west of Ogden City. The majority of the combined flow enters the Great Salt Lake through the Ogden Bay Refuge. The flow entering the Great Salt Lake from the Jordan River originates in the Wasatch Mountains that surround Utah Lake. The main tributaries above Utah Lake are the Provo and Spanish Fork Rivers at 11,000 and 9,500 foot elevations respectively. The Jordan River begins at the outflow from Utah Lake and flows northward through Salt Lake County to the Lake. Several streams from the west slopes of the Wasatch Mountains enter the Jordan along its path to the Great Salt Lake. Physiography of Region The Great Salt Lake Drainage Basin is composed of extremes in land- c form topography and geology. The Great Salt Lake Desert area to the west of the Lake is characterized by low mountain ranges separated by desert basins. On the east shore of the Lake, the western front of the Rocky Mountains rise abruptly from the valley floor to elevations as high as 11,000 feet. The mountains extend throughout the drainage of the Bear, Weber, and Jordan Rivers, accounting for 90- 95 percent of the total surface |
