Californians were leaning against borrowing $9 billion for water projects Tuesday in a state where water scarcity often pits city dwellers, farmers, anglers and environmentalists against one another. About 53 percent of voters opposed Proposition 3 with about 3.6 million votes counted. The bond measure devoted money to storage and dam repairs, watershed and fisheries improvements, and habitat protection and restoration. Much of the $8.9 billion was earmarked for conservancies and state parks to restore and protect watersheds, and to nonprofits and local agencies for river parkways.
