(d) If unappropriated flood waters apportioned to Texas are stored in facilities constructed in New Mexico, the following principles shall apply: (i) In case of spill from a reservoir constructed in and operated by New Mexico, the water stored to the credit of Texas will be considered as the first water to spill. (ii) In case of spill from a reservoir jointly constructed and operated, the water stored to the credit of either state shall not be affected. (iii) Reservoir losses shall be charged to each state in propor- tion to the quantity of water belonging to that state in storage at the time the losses occur. (iv) The water impounded to the credit of Texas shall be released by New Mexico on the demand of Texas. (e) Water salvaged shall be measured at or near the Avalon Dam in New Mexico and to the quantity thereof shall be added a quantity equal to the quantity of salvaged water depleted by man's activities above Avalon Dam. The quantity of water salvaged that is appor- tioned to Texas shall be delivered by New Mexico at the New Mexico- Texas state line. The quantity of unappropriated flood waters impounded under paragraph (d) of this Article, when released shall be delivered by New Mexico at the New Mexico-Texas state line in the quantity released less channel losses.

ARTICLE X The failure of either state to use the water, or any part thereof, the use of which is apportioned to it under the terms of this Compact, shall not constitute a relinquishment of the right to such use, nor shall it constitute a forfeiture or abandonment of the right to such use.
