The Flume is a modern aqueduct carrying irrigation water over the Pecos River. Construction took place from 1889 to 1890 and was part of the Pecos River Reclamation Project. It was originally constructed of wood and spanned 145 feet (44 m). It carried water at a depth of 8 feet (2.4 m). In 1902, a flood destroyed the Flume and it was subsequently rebuilt using concrete. In 1902, it was the largest concrete structure in the world. (Wikipedia)The Flume is located in Carlsbad, NM, and now belongs to the city. There is a beautiful walking path along the river with benches placed along the way where you can sit and watch the flowing river or feed the very friendly ducks.
