Lake ecology

Water quality, algae, stratification, oxygen, invasive species, wetlands, fish habitat, and shoreline basics.

Lake ecology

A lake is a living system, not just a blue shape on a map. Light, oxygen, temperature, nutrients, plants, fish, wetlands, and shoreline choices all interact.

Deep lakes can stratify into layers. Shallow lakes can warm quickly. Nutrients can feed algae. Shorelines can protect habitat or expose the lake to erosion and runoff.

Good lake pages should connect size and depth to ecology, conservation, public use, and local observations.
