Cold Water Conservation Areas

Overview

This dataset identifies the State’s remaining watersheds that still support native fish species dependent on pristine, cold water habitats.

Data Layer Description

Location

Maryland

Scale: unknown

Description

In Maryland, certain freshwater fish species require a combination of cold water stream habitat and pristine stream conditions in order to survive and reproduce.  These cold water dependent species, such as Brook trout, typically cannot survive when water temperatures exceed 68 degrees Fahrenheit. Anthropogenic alterations to Maryland’s environment, such as forest clearing for development and agricultural production, have altered the extent of pristine, cold water habitats.  

The Cold Water Conservation Areas dataset is based on field surveys conducted by the Maryland Biological Stream Survey and the Maryland Fisheries Service and other participating federal, state and county resource agencies that note the presence of pristine, cold water habitat dependent fish species.  Watershed areas supporting these habitats have been identified as a land conservation priority in order to maintain habitat conditions needed to sustain these fish populations.

How you might make use of this data layer

This data layer identifies watersheds that native fish species dependent on pristine, cold water habitats.  These watersheds are sensitive to factors that result in thermal impacts, such as land clearing, increases in impervious surface, warm water discharges and climate change.
