•ArcView was used to quickly create bathy- metric data, perform editing, and create cartographic output.
•ArcPad's simple API saved time.
•GIS helps to accurately apply herbicide to targeted areas.
Saratoga Lake is a 4,000-acre lake located in Saratoga County, New York. The highly invasive Eurasian watermilfoil weed was reportedly introduced to Saratoga Lake in the mid-1970s and reached nuisance densities by the early 1980s. Planning efforts began in 1982, and in 1986 a mechanical harvesting program was initiated to cut and remove the weed from the lake. The Saratoga Lake Protection and Improvement District (SLPID) was created in 1986 to oversee the harvesting operations. Harvesters were operated between mid-May and mid-September each year. While simultaneous watershed management efforts improved water quality, the Eurasian watermilfoil infestation became worse. By the mid-1990s, most of the lake perimeter less than 15 feet deep supported dense Eurasian watermilfoil that would grow to the surface and greatly interfere with recreational boating and swimming, not to mention adversely impact fish, wildlife, and water quality. The harvesting program simply could not keep up with the proliferating plant.
