Casco Bay Estuary Partnership (CBEP) is engaged in on-going efforts to collect water quality monitoring information for Casco Bay. In 2016, CBEP created a Casco Bay Monitoring Network to identify shared monitoring priorities among the growing number of entities who are monitoring the waters within Casco Bay and its watershed. In 2016-2017, 14 organizations provided water monitoring information for each of their programs and the parameters collected within Casco Bay. The information is available in kmz format for Google Earth and as shape files for ArcMap.

Click here for Table 1, which provides summary information on 31 monitoring programs and whether they are collecting information in the following parameter groupings: biota, nutrients, sediments, tidal wetlands, toxics, and water quality.

The Casco Bay Monitoring Network in 2019 is involved in reviewing and revising the Casco Bay Monitoring Plan.

The original plan, “Measuring Progress, The Casco Bay Monitoring Plan,” was completed in 1996 and is available here.

The 2004 revision, “Casco Bay Environmental Monitoring Program,” is available here.

A discussion of implementation of activities from the 1996 and 2004 Monitoring Plans is available here.

Casco Bay Estuary Partnership’s State of the Bay Report for 2015 is available hereĀ  and for 2010 is available here.
