Freshwater Flow into Chesapeake Bay Active
Explore resources here describing estimates of freshwater flow entering Chesapeake Bay.
The health of the Chesapeake Bay is greatly affected by freshwater flow from rivers draining its watershed. The amount of freshwater flow (also called streamflow) will:
• Change salinity levels in the Bay, which affect oysters, crabs, and finfish.
• Influence the amounts of nutrients, sediment, and contaminants delivered to tidal waters, which affects fisheries and submerged aquatic vegetation.
The USGS provides estimates of the monthly and annual amounts of freshwater flow into the Bay so scientists and managers can better understand effects on ecosystem conditions.

Below are resources describing Chesapeake Bay streamflow estimation methods, the history of programming the Chesapeake Bay Streamflow interactive website, and other science projects and research associated with Chesapeake Bay estimated streamflow, such as work characterizing Chesapeake Bay Water-Quality Loads and Trends.

Chesapeake Bay Estimated Streamflow: METHODS
Methods for Estimating Streamflow to Chesapeake Bay The following is a description of how data presented on the website "Chesapeake Bay Estimated Streamflow" are computed. Essentially, the methodology was published more than 51 years ago, and has been adapted for use in modern automated computing systems. Approaches for summarizing data and describing it using statistics follow standard practices...Chesapeake Bay Real-Time Streamflow Map

by Brad Garner, Hydrologist USGS This website originated as a dynamic web application (hereafter, simply webapp). That is, content such as data and graphs, were generated "on-the-fly" as requests were made by web-browser clients. This was made possible by automating the methods of Bue (1968), and by using dynamic web-content software technology. Beginning in 2019 the original dynamic web...Chesapeake Bay Water-Quality Loads and Trends
Access the most recent data gathered from the Chesapeake Bay Nontidal Monitoring Network , learn about the techniques used to collect this data, and read about the history of the Chesapeake Bay Nontidal Monitoring Program. Nontidal Network (NTN) data refers to data from the 123 monitoring stations where nutrients and sediment are collected monthly and during storms. River Input Monitoring (RIM)... - Partners
