The longterm response of lakes in the northeastern United States to different levels of acidic deposition was predicted by using a lumped parameter hydrologic/biogeochemical model, the Enhanced Trickle-Down Model. Eighty-one lake watersheds were simulated for a 50-year period with constant levels of acid deposition and a 30 percent decreasing ramp function of acid deposition. Results indicated little response under constant loading, but seven percent of the lakes recovered from acidification when acid deposition was decreased. Uncertainty of the results was estimatE via a first order second moment analysis.
