Technical Memoranda (TM) presenting the results of surface water monitoring surveys conducted by the Watershed Planning Program (WPP) from 2005 through 2011 are presented below, grouped by watershed. The TMs related to water quality monitoring contain project-specific data and related metadata that are also provided on the “Data” page.  The TMs pertaining to primarily biological information (e.g., benthic macroinvertebrates, periphyton, fish populations) contain biological data and metrics that are currently not reported elsewhere. For reports containing data and information from prior to 2005, see WPP’s Water Quality Assessment Reports. Also, additional data on Central Regional watersheds (Blackstone, Nashua, Concord, French-Quinebaug, Millers and Chicopee) can be found on MassDEP's SMART Monitoring Technical Memoranda web page.  From 2010 to 2015, the Watershed Planning Program focused the majority of its monitoring efforts on a probabilistic survey of wadeable rivers and streams throughout Massachusetts. The summary report for this work will be available in 2017.
