If you've never seen them, the Energy Information Administration (EIA) has fairly interesting natural gas weekly updates on its website.  A sample regarding Canadian imports, for example:  "Net imports of natural gas via pipeline from eastern Canada into the northeastern United States this past winter (November 1, 2012 through March 31, 2013) averaged 1.06 billion cubic feet per day (Bcf/d), less than half of the five-year average of 2.14 Bcf/d, according to data from BENTEK Energy, LLC (Bentek)."
