San Francisco ? Although analysts haven’t finished calculating the total cost of rerouting two humpback whales that strayed into the Delta last month, the bill to taxpayers is in the six figures.

The massive rescue effort spanned more than two weeks and involved 35 groups, including agencies at every level of government and multiple nonprofit organizations.

Three of the operation’s most visible agencies were the state Department of Fish and Game, California Highway Patrol and the state Governor’s Office of Emergency Services, which together spent an estimated $240,000 on the effort, according to OES spokesman Eric Lamoureux.

About 60 percent of the $240,000 was incurred by the state Department of Fish and Game.

And the CHP dipped into its emergency contingency fund to the tune of about $50,000 so that eight officers a day could control the sightseeing traffic the whales generated. The funds also covered the use of an airplane and, on occasion, a helicopter.
