<br />~ The Forum accepts the suggestion and deletes the <br />~ sentence. <br />o <br />0) The Navajo Nation <br /> <br />The Navajo Nation shares with the Forum the general <br />concern over inoreasing salinity of the Colorado River, but <br />is concerned that needed growth will be hampered by salinity <br />control requirements. They are also concerned that future <br />attempts to oontrol the Blue Springs may result in aotivities <br />contrary to the religious beliefs of the Navajo and Hopi <br />peoples. <br /> <br />The intent of t~e Forum is to maintain the adopted <br />salinity criteria while the basin states continue to develop <br />their compact-apporti9ned waters. The control measures <br />included in the plan pf implementation consist of federal <br />and non-federal actions encompassing, existing man-made and <br />natural sources, as w,ll as future development. <br /> <br />In 1974, when the Forum was investigating salinity <br />sources and possible control measures, consideration was <br />given to Blue Springs, a significant point source. However, <br />because of its special religious significance to the Indian <br />people and other factors, the Forum decided not to include <br />Blue Springs as part of the implementation plan. <br /> <br />Environmental Defense Fund (EDF) <br /> <br />Salt Routing St4dief - EDF suggests that, in addition <br />to Figures 2, 3, and ,t e results of all of the salt rout- <br />ing studies should have been included in the report. <br /> <br />The Forum disagrees with this suggestion. See comments <br />on page 5 under the heading Environmental Protection Agency, <br />Salt Routing Studies. <br /> <br />Change in Flow Versus Salt Load Relationshi~s - EDF <br />questions the Forum's conclusion that a change in flow versus <br />salt load relationships has occurred in recent years stating <br />that the salinity at Lees Ferry in 1976 is only 10 mg/l below <br />that in 1972. <br /> <br />The Forum's conclusion was based on a preliminary <br />analysis of records beginning in 1941 for Lees Ferry, 3ta- <br />tions above Lees Ferry, and on the lower main stem of the <br />river. On the lower main stem, 1976 salinities are nearly <br />60 mg/l lower than those in 1972. Due to reservoir storage, <br />a lag of about two years exists between Lees Ferry and lower <br />main stem stations. Therefore, a comparable period for Lees <br />Ferry would be 1970 through 1974. During this period, the <br />decrease in salinity at Lees Ferry was 83 mg/l. <br /> <br />The Forum appreciates the reference to the article in <br />Science magazine (Vol. 202, pgs. 629-631, November 10, 1978) <br /> <br />11 <br />
