The state released an $8.9-billion proposal in 2007 that involved building a horseshoe-shaped outer lake, a berm crossing the center of the lake and an extensive system of dikes, channels and pumps. Due to their concerns about the impact on the lake, the district only approved the water transfer agreement after Governor Gray Davis had signed the 2003 legislation known as the Salton Sea Restoration Act. It said it is the "intent of the Legislature that the State of California undertake the restoration of the Salton Sea ecosystem and the permanent protection of the wildlife dependent on that ecosystem". The restoration plan was not implemented as state lawmakers found it too expensive and the Great Recession hit the economy. Repeated delays and dwindling public interest precluded any real change.
