Working with the watershed

Adding limestone to acidified lakes has proved an effective and environmentally sound method of restoring populations of game fish and other aquatic life. Building on successful experience with lake liming, researchers are now going a step further by liming a water-shed - the land surrounding a lake - rather than the lake itself. Applied by helicopter, the limestone dissolves and saturated the ground with calcium ions, which neutralize acidic runoff before it reaches the lake. Researchers are interested in whether deep soil layers are neutralized and how that affects the duration of treatment. Over the next two years, researchers will measure changes in soil and in the acidity of the lake and its tributaries, as well as monitor effects on aquatic life. A parallel experiment in West Germany will lime a forested watershed to study effects on the terrestrial ecosystem. An objective of both projects is to evaluate a computer model that simulates lake-watershed processes.
