Report of the Instream Flow Pilot Program

This report describes the findings and recommendations of the Instream Flow Protection Pilot Program (Pilot Program). The purpose of the Pilot Program was to develop a methodology to define and implement protected instream flows on Designated Rivers and to meet water quality standards. The Pilot Program developed a method of protecting water quantity by establishing numerical criteria that appropriately represent the natural variability of flows on the Souhegan and Lamprey rivers. The Pilot Program’s protection criteria were established and management plans were adopted August 30, 2013; and implementation of the water management plans was studied over the next two years. This report encompasses the protected instream flow studies, development of the water management plans, and the first two years of implementation on these two rivers.

The final report of the Instream Flow Protection Pilot Program is below. This report is the statutorily required evaluation of the Instream Flow Protection Pilot Program, submitted pursuant to RSA 483, Chapter 201 of the Laws of 2009, and Chapter 248 of the Laws of 2013.

A Draft Report was distributed September 1, 2015. The public was invited to submit comments on the DRAFT Report of the Instream Flow Pilot Program. The public comment period was open September 1, 2015 through October 25, 2015.
