Narrows is a term for restricted land or water passages. Most commonly it refers to a strait, though it can also refer to a water gap.

A narrows may form where a stream passes through a tilted bed of hard rock lying between two softer beds: "[i]f the hard beds are vertical, so that their outcrop does not shift as erosion proceeds, a narrows is developed".[1] Like a dam, this "raises the water level for a short distance upriver".[2] A narrows is also typically a good location for trapping migrating fish.[3][4][5] Furthermore, a narrows is "an important topographical feature for wind mixing",[6] an effect where a wind chill may form ice while the surrounding temperature remains above freezing.
