Lakes In The Landscape

NTL researchers developed the "lake landscape position" concept to explain spatial variability in water chemistry and community composition that results from a shifting balance of groundwater, surface water, and precipitation inputs to adjacent lakes.

Increases in fish species richness as a function of landscape position in the Northern Highlands Lake District of Wisconsin, including North Temperate Lakes LTER study lakes. Lakes high in the landscape fed predominantly by precipitation have negative lake position scores and few fish species; lakes low in the landscape fed largely by groundwater as well as surface water have positive lake position values and provide habitat for many species of fish.
