The James River Watch (JRW) is a real-time map of conditions on the James River. It incorporates river height, water temperature, and air temperature data to show boating conditions on the upper James River. It also displays three day forecasts of sea-nettles, harmful algal blooms, and bacteria in the lower James as well as data from two NOAA monitoring buoys on the lower James. Data to update the map is pulled dynamically from websites maintained by the United States Geological Survey, the National Weather Service, the National Oceanographic and Atmospheric Administration, and the University of Maryland. Conditions on the map are updated as often as every 15 minutes.
CEC updated the JRW in 2013 with functionality that allows the James River Association’s monitoring volunteer to upload data, pictures, and reports to the site. Once approved by a site administer, this information then shows up on the JRW map. Site admins can also add new monitoring stations to the map, add monitoring volunteers, and perform various site maintenance functions,
The JRW was developed using php and the Google Map API and run on a MySQL database.
