SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

Q&A

Question: How much variation in flows from the Relief Tunnel Drainage system is to be anticipated. Is historical data of flows from the drainage system available?

ANSWER: Flows in the relief tunnel are not typically seen when reservoir elevations are below 1135’. During the flood season, November through March, the reservoir pool drops to 1075’ to make space for flood storage. During a typical flood season, the 1135’ elevation is exceeded 2 to 3 times during heavy storms. The exceedance duration is typically 4 to 5 day.

The max flows through the relief tunnel are observed during max pool, elevation 1206’. Flows can reach .75 cubic feet per second. The max pool is held during late Spring and early summer for fish conservation. Max pool has never been reached during a flood. The flood of record, occurred in 2009, and resulted in the reservoir reaching elevation 1189.

The above conditions are described as typical. Number of storms and their intensity varies from year to year. As weather in unpredictable, the government makes no guarantees on what conditions will be experienced and Howard Hanson Dam.
