U1 Alternatively basing conservation on Lake Orange levels allows the prime storage to be the determining factor. It is right now the only means of withstanding a lengthy drought. It is therefore recommended that the ordinance provisions relating to it remain in effect. A second recommendation is that the Board revise Table II in respect to: 1. Triggering stage II at 80% rather than 90%. This would avoid going in and out of alerts too frequently. 2 . Permitting instream flow of 1.1 million gallons from 100% down to 80%; 650, 000 gallons from 80% to 60%, 390,000 gallons from 60% to 40%, and 0 gallons from 40% to 0 lake volume. This is per the recommendation of the Division of Water Resources. Thirdly, it is recommended that a different staging table be put into effect if a drought starts earlier in the season as it did this year. Normally water scarcity begins in September and runs through November. This year, however, shortfalls were evident as early as last Fall 's (1985) dry weather through the Spring. This prompted having to start releases in late May versus September. Whenever this reoccurs there should be provision in the ordinance to signal a different procedure. Possible wording will be distributed as soon as it is ready. IMPACT: Improve administration of the ordinance. RECOMMENDATION(S) : 1. Retain Lake Orange elevation levels to activate the stages under the ordinance. 2 . Alter Stage II to begin at 80% of usable storage rather than 90% . 3 . Permit instream flow of 1.1 million gallons from 100% down to 80%; 650, 000 gallons from 80% to 60%, 390, 000 gallons from 60% to 40%, and 0 gallons from 40% to 0 lake volume. This is per the recommendation of the Division of Water Resources. 4. Direct staff to explore wording to account for seasonal variation in any drought management strategy and procedure.
