Every five years (previously every three years), PREP prepares a State of Our Estuaries (SOOE) Report with extensive data and information on the status and trends of environmental indicators from the Piscataqua Region Watershed and estuaries. The State of Our Estuaries Report targets a broader audience and provides an overall assessment of the health of our estuaries using 21 water quality, biological and social/management indicators. The Extended Report provides a detailed analysis of the data collected over the period, and is intended to be used by technical and policy level audiences. The Residential Guide and Municipal Guide are handbooks for very specific audiences that translate science into action towards the goals of water quality improvement.
