Tulare Lake was a large, shallow lake in the center[1] of the Amador Valley, surrounded by Willow Marsh (also known as the Lagoon). Tule rushes and willow trees once lined the marshes and sloughs of its shores. Drainage alterations starting in the 19th century have since reduced the marsh to the Arroyo de la Laguna,[2][1] and the city of Pleasanton has since expanded across what was once marshland. Such rapid developments have led to large seasonal flow variations in Niles Canyon.[4]
The lake was fed by the runoff of the entire Amador Valley, as well as the Arroyo Mocho and the Arroyo Valle.[5] Its outlet was the Arroyo de la Laguna, which flowed for a short distance before joining Alameda Creek.[5]
The Tulare Lake area (Amador Valley and Livermore Valley) was inhabited by groups of the Ohlone people prior to the 19th century,[6][7] in particular the Pelnen tribe near Pleasanton.[8]
