Lake I8

Bathymetric Map

Manipulation

Lake I8 has been part of a long term fish density manipulation since 1989. The manipulation involves removing low numbers of fish each summer to simulate fishing pressure on a system.

Lake Description

For a full description see: Kling G.W. et al. 2000. Integration of lakes and streams in a landscape perspective: the importance of material processing on spatial patterns and temporal coherence. Freshwater Biology, 43, 477-497.

Lake I8 is at the same elevation as lake I7, but not a portion of the I1-I7 lake chain (map). I8 has one major inlet in the form of a tundra stream which enters on the southwest side of the lake.
