Environmental Concerns for the Bass

As of 2020, one of the biggest environmental concerns for the Bass River is rising nitrogen levels due to the installation of septic tanks in surrounding towns. Increased nitrogen concentrations lead to algal growth, which depletes the oxygen in the water and makes the river unsafe for recreation. See water quality for many of Cape Cod's waterbodies on APCC's State of the Waters: Cape Cod 2020 >>
