Mishak Lakes Preserve
A Key Breeding and Migratory Habitat for Wetland Birds

Preserve Highlights    
This is one of the largest flourishing wetland complexes in Colorado. It consists of dozens of shallow seasonal ponds in the San Luis Valley basin - an oasis nestled amongst a mountain backdrop.

Waterfowl and shorebirds, including American avocet, Wilson's phalarope, greater sandhill crane and white-faced ibis, thrive here.

Why The Conservancy Selected This Site  
Because it is one of the state's most important breeding and migratory habitats for wetland birds. It also plays host to several globally rare plants and insects.

What The Conservancy Has Done/Is Doing
The Conservancy's foremost goal is to preserve the natural processes that supply water to this wetland complex, thereby also protecting the endemic species that live here.

The health of this wetland system depends on a complex relationship between precipitation and ground and surface water. The preserve's dozens of shallow seasonal ponds typically dry out by mid-summer, but late-season rain can fill the lakes again in August. Although water levels may fluctuate dramatically from year to year, plants and animals living here are well adapted to these cycles.

We also are working within the local community to create partnerships in conservation and education.
