The numbers are staggering – 500,000 septic tanks on Long Island. An estimated 2000 outfall pipes pouring runoff into our lakes, streams and bays with each rain. 100+ small dams and spillways blocking the way for ocean fish that would otherwise spawn. Clam harvests in the Great South Bay down well over 90 percent. Scallops in Peconic Bay all but wiped out by rust tide. Fish populations a small fraction of what they were not too long ago.
