摘要

Lake Zapotlan is a small (1100 ha) endorheic lake in western Mexico. The lake is an internationally recognized RAMSAR site, home to many migratory species of waterfowl. It receives point source pollution from partially treated sewage from Ciudad Guzman (population 85,000) and Gomez Farias (population 12,000), as well as non-point sources, including storm water, agricultural, and land clearing runoff from numerous farms and from deforestation surrounding the lake. Anthropogenic activities in the basin are putting the ecological sustainability of the lake at risk. The lake is hypertrophic and exhibits blooms of green algae and possibly cyanobacteria throughout much of the year. Along the shoreline of the lake, extensive beds of bulrush, called locally "rule" (Typha latifolia), are found, as well as floating mats of water hyacinth (Eichhornia crassipes) likely due to excessive nutrient levels in the lake. This paper compares nutrient levels (nitrogen and phosphorus) for three different years since 1994.
