To test the efficiency of watershed liming in western Maryland to mitigate acidification, Alexander Run (a small, first-order Garrett County stream draining into the North Branch of the Casselman River) was selected. The effect of limestone application on water chemistry and the macroinvertebrate and fish community of Alexander Run was monitored from 1990. Pelletized limestone was applied to the watershed between 21 - 23 October 1991. Biological data collected from Little Bear Creek (macroinvertebrate and fishes), an unnamed tributary to Herrington Creek (macroinvertebrates), and Big Run (fishes) were employed to assess changes in stream biota in two Alexander Run stations (upper and lower). The objective of year three (1992-1993) was to continue post-liming monitoring through July 1993 in order to assess long-term effectiveness of watershed liming.
