Abstract/Description  
This report explains techniques used to estimate monthly, annual, and low 7-day, 10-year (7Q10) streamflows for Maine rivers.  Ten years of data for over twenty rivers were used to create the regression models that are at the core of the estimation technique.

The models allow five factors to be used in streamflow estimates; these relate to the are ao fthe drainage basin of a river, how far it is from the coast, rain and snow fall, and whether sand and gravel aquifers are present and how large they are.  The results showed that if a river has a drainage basin closer to the coast, the river will have higher winter streamflow but lower spring and summer streamflow, probably because inland streams are fed by melting snow in the spring. If a stream has a sand/gravel aquifer underneath its drainage basin, it will be better able to compensate for low flow conditions.
