The year recurrence interval means that a flood of that magnitude has a one percent chance of occurring in any given year. In other words, the chances that a river will flow as high as the year flood stage this year is 1 in Statistically, each year begins with the same 1-percent.

And to define water quality, it is imperative to make long-term, national measurements. Much information on the water quality of New Zealand rivers at national scale has come from monitoring at 77 sites in the National Rivers Water Quality.By the early 19th century, Atlantic Salmon runs in New England, which historically occurred in almost every major river north of the Hudson River, were severely depleted.

By the end of the 19th century, Atlantic Salmon had been extirpated from three of the five rivers with the largest populations (Androscoggin, Merrimack, and Connecticut Rivers).A recent MIT news spotlight on research for detecting bacteria brought to mind 19th century research on water quality in Massachusetts.
