The Reach of the Public Trust Doctrine (2 of 4)


Navigable Waters (Continued)

State Definition

  • Navigable Tidewaters
    All states regard tidewaters as navigable waters regardless of whether the waters are actually navigable. All lands beneath or subject to the ebb and flow of tidewaters are subject to the Public Trust.

    States own these lands in trust for the public. The exception is in those Atlantic states where private ownership extends from the upland to the low water mark. You will recall from Module 1, however, that even in these states the private land is subject to a public easement for recognized Public Trust uses.
  • Navigable Freshwaters
    States apply different measures to determine whether freshwaters are navigable. States also vary as to whether lands beneath navigable freshwaters are in public ownership. But regardless of ownership, navigable freshwaters and the lands beneath are subject to a public easement for recognized Public Trust purposes.
