The Isinglass River in Strafford County, southeastern New Hampshire, the United States, is about 15 miles (24 km) long.[1] It rises at Bow Lake in Strafford, but is also fed through its tributaries by Ayer's, Nippo, Round and Long Ponds in Barrington. The Isinglass flows east to meet the Cochecho River below Rochester. The river is part of the Piscataqua River watershed.

In History of the Town of Rochester, N.H., published 1892, author Franklin McDuffee remarks that the Isinglass River is "probably named from the mica in its bed or along its banks." Isinglass is a synonym for mica, an abundance of which makes rock at the Isinglass River sparkle.

Why Fish the Isinglass River
  • Native Species:  American Eel, Chub, Suckers, Pumpkin Seed/Sun Fish, Perch, Golden Shiner, Black Nose Dace. Hundreds of years ago, the Isinglass, as a feeder stream of the Cocheco, sustained Atlantic Salmon runs.
  • Non-Native Species:  Small Mouth Bass.
  • Stocked Fish: The NH Fish & Game stocks in the spring only. Rainbow and Brown Trout, and Brook Trout. 
  • Location:  A short drive from all points in southern NH and Boston, MA. 
  • Experience:  In multiple pull-off locations, there are several spots that are easily accessed by foot.  The river is heavily fished.  Adventuring away from the well fished spots will not produce tons of fish, but on occasion, a trout will come to your fly.
  • Size: due to the size of the river, this is strictly walk-n-wade fishing.
  • Structure and Depth:  Varies greatly.
  • Scenery:  Some spots are very picturesque, but you are never far from a house and road.
