| Abstract |
The integrated Lake Watershed Acidification Study (ILWAS) model was used to simulate the recovery of the highly acidified Clearwater Lake, Ontario. These decreases in acidic constituents are in good agreement with monitoring data. Longterm simulations indicate that deacidification may continue until approximately 2020, if S deposition rates remain at or below the 1987 level. The agreement between simulated and monitoring data for the first 10-a of recovery and the simulated long-term recovery of the lake to its pre-smelter level of acidity lend confidence in the capability of numerical models to simulate the reversibility of watershed acidification and suggest that some highly acidic watersheds may eventually recover, given substantial decreases in acid deposition. |
