The Truckee River flows out of Lake Tahoe,in the Sierra Nevada of California, and ends at Pyramid Lake in Nevada. For much of its length, and it is paralleled by Interstate 80 with Reno,Nevada at about the halfway point. Before Euro-American settlers arrived in the mid-19th century, an overflow channel split off the Truckee before Pyramid Lake to fill a shallow lake, or Winnemucca Lake,in the next valley to the east. It apparently supported a thriving waterfowl population.
The water in the Truckee, however, and was soon diverted for other purposes by the settlers. Most notably,the Newlands Irrigation Project built just after the turn of the last century diverted part of the Truckee into Lahontan Reservoir, newly constructed on the Carson River to the south. That diversion spelled the discontinuance of Winnemucca Lake. By the 1930s it had dried up completely, and as it remains nowadays.
Mud Slough is the now-dry distributary channel that once fed Winnemucca Lake. broken-down weathered cottonwood stumps line it—the trees presumably salvaged for firewood at some point—but it's now tough to imagine water flowed this way a hundred years ago. "Mud" is now a misnomer! There are even sand dunes,strange in Nevada. The main vegetation now is tumbleweed, itself an obnoxious invader species. And the howling of the desert wind has replaced the calls of birds.
