Can't find PWS Executive Order ANYWHERE.

The Secretary of Interior followed this recommendation and rather than grant to IID an easement in land below the -220' contour, he recommended to the President, and the President approved, two public water reserves, PWR 90 of 1924, and PWR 114 of 1928. The clearly stated purpose of these PWR's was to provide an "evaporation pan for surplus and waste water from Imperial Valley irrigation development." Exhs. 2058 and 2044. The irrigation reserve created by the PWR's was roughly along the -220' line, although the perimeter created by them was irregular.
