COLLECTED INFORMATION

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. The Monitoring Network acts as the stewards of monitoring in the Bay and ensures that monitoring is adaptive to changing circumstances. 

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.
