In 2012, EPA-NCEA released a report on the implications of climate change for stream bioassessment programs. The report identified the need for biological, chemical, and physical monitoring data capable of detecting climate change effects in stream ecosystems. These data needs included continuous measurements of temperature and flow in ungaged streams. Understanding long-term trends in various types of stream data (such as water temperature and flow) is important to detect and track the impacts of climate change. Currently, there are not many sources of continuous data (measured constantly over 24 hours a day and seven days a week) on temperature and flow in free-flowing freshwater wadeable streams; this makes it challenging to analyze long-term trends in these parameters.
Several EPA Regions and states requested that EPA compile methods for deploying continuous temperature and flow sensors. This report describes the current “best practices” for state and EPA regional biologists considering the deployment of continuous temperature and flow sensors in wadeable streams.
|Jan 2013||EPA, in collaboration with the Massachusetts Department of Fish and Game, U.S. Geological Survey, and U.S. Forest Service, held webinar for state and EPA regional biologists to discuss methods and gauge interest in a best practices document.|
|Oct 2013||EPA released the external review draft document for public review and comment. [Federal Register Notice Oct 31, 2013]|
