Trout Streams Forever

Preserving our coldwater stream aquatic ecosystems for future generations

Protecting the health of our coldwater stream ecosystems

Trout Stream Aquatic Macroinvertebrates

Mayfly, caddisfly, and stonefly larvae are the "Canaries in the Coal Mine". Scientists have proven around the World, that aquatic insect's diversity and density can be used to determine the health of a stream. Unfortunately, many important aquatic insects are declining.

Monitoring the Stream Macroinvertebrates

Scientists have studied the aquatic macroinvertebrates living in the benthic zone of our cold-water streams and have identified aquatic macroinvertebrates species that are the least tolerant to organic pollution, and species  that are extremely tolerant to organic pollution.

Chemical Warfare on our Trout Stream Ecosystems

It may seem harsh saying we are causing chemical welfare on our coldwater aquatic insects and trout stream ecosystems, but in reality it is true. Scientists are now pointing to Neonic pesticide products as a major cause for the decline of our mayfly, caddisfly, and stonefly populations in many of our coldwater trout streams. Compounding the problem are organic sediments running into our streams from rain runoff and floods. Fortunately, it is not too late for us to solve these issues, or at least dramatically reduce them.
