​LARGE COLD SPRINGS IN BIG MEADOWS (PLUMAS 8). Large springs issue at the northeast edge of Big Meadows, about 5 miles by road northeast of Prattville. The water issues from ba- saltic lava, a few feet above the meadow level, in an area of willows and quaking aspens about 100 yards in diameter. After flowing down over rimes of coarse lava gravel it forms a sluggish stream 100 yards or more in width in the meadow. A very rough float measurement LARGE COLD SPRINGS. 331 at the riffles indicates that the discharge is about 56 second-feet (29,000 gallons a minute). The water is cold (46°) and of very good quality. It has been used to some extent for irrigating the meadow and forms a tributary of North Fork of Feather River.SPRINGS OF CALIFORNIA BY GERALD A. WARING
