Tatnuck Watershed Studies and Reports

Urbanization impacts on stream and lake water quality in a small watershed in central Massachusetts, USA. Laura C. Reynolds et. al. This study examines the influence of urbanization on the chemical characteristics of Tatnuck Brook Watershed. Field measurements and laboratory analyses were conducted at 13 stream, lake, and tributary sites during the 2022 field season for conductivity, nutrients (nitrate, ammonia, total phosphorus), and trace metals (Cu, Pb, Zn). Land cover analysis of subwatersheds for showed a gradient of urbanization from predominantly forested headwaters to densely developed downstream sites. 

Coes Pond and Stormwater Management 2015 WPI MQP report by Adam Weis and Brendan Kling. This project determined stormwater and nutrient loadings for Coes Reservoir and designed a stormwater treatment unit to reduce nutrient loading to the reservoir. Note that since this report was written the city installed a stormwater treatment unit at this site as part of the Coes Reservoir Boardwalk project.
