From the beginning, the mineral springs near the lake attracted visitors seeking therapeutic treatments. In 1887, the Crescent Bath House, now known as "The Chimes", was built; it still stands in historic downtown and is a registered national historic site. By 1888, the economy was supported by coal and clay mining at what became the town of Terra Cotta, gold mining in the Pinacate Mining District, ranching, and the agriculture of fruit and nuts. After 1893, the lake's water level sank almost continuously for nearly 10 years, with a slight rise every winter. Heavier precipitation, beginning in 1903, gradually filled the lake to about half the depth above its minimum level since 1883. Then, in January 1916, a flood rapidly raised the level to overflowing.
