Compact provisions.
The provisions of the Oregon-Washington Columbia River Boundary Compact are as
follows:
______________________________________________________________________________
ARTICLE
I.
PURPOSE
The boundary
between the States of Oregon and Washington along the course of the Columbia
River has not been easy to ascertain because of changes in the main channel of
the river with a result that a state of confusion and dispute exists and the
enforcement and administration of the laws of the two states has been rendered
difficult.
The purpose of
this compact is to fix with precision by reference to stations of longitude and
latitude the boundary between the States of Oregon and Washington from one
marine league due west of the mouth of the Columbia River to the most easterly
point at which the 46th parallel of north latitude crosses said river, at which
point the river ceases to form the boundary between the two states.
ARTICLE
II.
DESCRIPTION
The boundary
between the States of Oregon and Washington from one marine league due west of
the mouth of the Columbia River to the point at which the last described point
number of the boundary as herein determined meets the 46th parallel of north
latitude at 118°5910.12 of the west longitude shall be as follows:
Beginning one
marine league at sea off the mouth of the Columbia River at north latitude 46°1500.00;
running thence due east to point number 1 of this description, which point is
at north latitude 46°1500.00, west longitude 124°0500.00; thence from point
number 1 continuing upstream in the channel of the Columbia River by a series
of straight lines connecting the following numbered and described points in
consecutive order.
