where does the meramec river start and end
Meramec River The Meramec River (/ˈmɛrɪmæk/) is one of the longest free-flowing waterways in Missouri, draining 3,980 square miles (10,300 km2)[1] while wandering 218 miles (351 km)[2] from headwaters near Salem to where it empties into the Mississippi River near St. Louis at Arnold and Oakville. The Meramec watershed covers six Missouri Ozark Highland counties—Dent, Phelps, Crawford, Franklin, Jefferson, and St. Louis—and portions of eight others—Maries, Gasconade, Iron, Washington, Reynolds, St. Francois, Ste. Genevieve, and Texas. Between its source and its mouth, it falls 1,025 feet (312 m). Year-round navigability begins above Maramec Spring, just south of St. James. The Meramec's size increases at the confluence of the Dry Fork, and its navigability continues until the river enters the Mississippi at Arnold, Missouri.
Condamine River The headwaters of the river rise on the slopes of Mount Superbus, part of the Main Range, before passing through Cambanoora Gorge. The river flows through the towns of Killarney and Warwick, while the tributary Gowrie Creek drains the slopes around Toowoomba. At Surat the Condamine turns to the south-west and becomes known as the Balonne River.[3] The Condamine descends 516 metres (1,693 ft) over its 657-kilometre (408 mi) course,[1] with a catchment area of 13,292 square kilometres (5,132 sq mi).[4] The water basin contains more than 1,800 wetlands.[5]
