Macri's Big Spring Symposium

Get the entire story of what happened on Big Spring Creek in Newville, Pennsylvania: the science, the politics, and the research. Learn what the stream was before the hatchery closed and what the stream is now. I have included scientific papers, reports, streaming audio, and video. This is Macri's Big Spring Symposium.  I have opened the Aquatic Institute for scientific education. There is no overkill here. The podcasts and videos are done in an easy going manner so hopefully it would be similar to a couple of us sitting down and having a drink while discussing these points...nothing too fancy or too academic but still trying to get the scientific points across. It is important to understand what has transpired in the last 13 years of this project.

Tight lines,
