Abstract

It can be shown that the average retention time is the most important factor in determining the needed time to reacidify a limed lake. For lakes with retention times longer than 3 years, the dissolution calcite from the bottom after liming will be of little or no significance. The reacidification time is determined by the lake retention time. For lakes with a retention time in the range from 0.5 to 3 years, the dissolution of calcite from the bottom will be able to prevent reacidification during a large part of the first year after liming after which the retention time will determine the reacidification rate. Lakes with retention times shorter than 0.5 year will not be able to maintain a stable water quality for longer periods of time. Acidification shocks may break through any time in the lake. Such lakes are therefore not very fit for lake liming strategies and may be handled more adequately with methods for running water.
