Water balance for Crater Lake, Oregon by Manuel Nathenson
Tables
| Table 1. Parameter values for yearly water balances for Crater Lake, Oregon. Precipitation po is value at Park Headquarters that will result in no change in level for Crater Lake, coefficient B is ratio of level change to precipitation greater than p0, supply is total water supply to the lake divided by the area of lake. Water loss from the lake is made up of leakage and evaporation, both expressed as volume divided by total lake area. |
 |
| Table 2. Parameter values for yearly water balances for Crater Lake, Oregon, obtained by various correlations of yearly change in water level with precipitation data for the 1962-1988 time period. Uncertainties are standard errors. P-values are from t test (two tailed). |
 |
| Table 3. Parameter values for yearly water balances for Crater Lake, Oregon, obtained by correlations of yearly change in water level with precipitation data for the 1962-1988 time period. Uncertainties are standard errors. P-values are from t test (two tailed). Average absolute deviation is the sum of the absolute values of the difference between measured and calculated water level divided by the number of years. |

| Table 4. Parameter values for yearly water balances for Crater Lake, Oregon, obtained by correlations of yearly change in water level with precipitation data for the 1962-1988 and 1931-1962 time periods. Water-level change as independent variable. Uncertainties are standard errors. P-values are from t test (two tailed) comparing each result for 1931-1962 time period to 1962-1988 time period. |
