Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity and Chlorophyll a for the Chesapeake Bay and Its Tidal Tributaries - 2007 Chlorophyll Criteria Addendum

Published: October 01, 2007

The Chesapeake Bay numerical chlorophyll a criteria and reference concentrations were derived to address specific water quality, human and aquatic life impairments when applied in specific seasons and to specific salinity-based tidal habitats.  EPA strongly encourages the states to adopt the harmful algal bloom-based numerical chlorophyll a criteria for tidal fresh and oligohaline tidal waters where algal-related impairments are expected to persist even after attainment of the Chesapeake Bay dissolved oxygen and water clarity criteria.  This is an addendum to the original report.
