Measured and calculated physical and nutrient parameters (1984 – present).
Physical and Nutrient Parameters (1942-1982).
Data consist of changes in Land cover in series of years: 1982, 1984, 2001, and 2006s Data Source: Chesapeake Bay Program
These are water quality monitoring data from a long term fixed location monitoring study of non-tidal stations located in the Chesapeake Bay and Ohio River watersheds. The data are collected from fifty-five stations for a time period beginning January 1986 and extending to the present./p> Data Source: Chesapeake Bay Program
Record describes one year of an on-going water quality monitoring project. A total of forty-nine mapping cruises were conducted on Maryland water bodies.Seven water quality parameters were measured: water temperature, salinity, conductivity, dissolved oxygen, turbidity, fluorescence and pH. Water depth was also measured. Water was sampled at approximately 0.5-m depths below the surface./p> Data Source: […]
Water quality monitoring data collected at seventy tributary stations. Samples at all tributary stations are collected monthly.
Non-tidal Monitoring Network Layer.
Watershed Model cover the 1984 to 2005 time frame and are updated annually as data become available. Data are largely supplied by the seven watershed jurisdictions but are also obtained from NPDES permit databases, including EPA
