| Figure 9. Water level for Crater Lake (above 1882.14 m elevation) and precipitation at Park Headquarters (1962-63) and average of values for Park Headquarters and North Rim adjusted to mimic Park Headquarters values (1964-88). Water year is July 1 to June 30. Water levels shown by broken line calculated using equation (6) from precipitation values shown. |
 |
| Figure 10. Water level for Crater Lake and daily precipitation at Park Headquarters averaged over years with low (< 150 cm/y) precipitation (Water years 1966, 68, 77, 79, 81, 88). |
 |
| Figure 11. Water level for Crater Lake and precipitation at Park Headquarters averaged over years with medium (> 150 cm/y & < 180 cm/y) precipitation (Water years 1962, 63, 64, 67, 69, 70, 75, 76, 80, 85). |
