Stockton Waterfront - What is the Bubbler System? When
the weather turns hot, algae in the Stockton Channel tends to cause odor
and make the water look green. To address this problem, a bubbler system
has been installed. This system will mix the water, reducing odors that
may otherwise occur when the weather gets warmer.Construction of the bubbler system began the week of March 6. The project is expected to be completed by May 2006. The Stockton ChannelThe Stockton Channel covers 42.9 acres, including the channel corridor, McLeod Lake, and the Stockton Yacht Harbor. The average depth of McLeod Lake and the Stockton Yacht Harbor is ten to fifteen feet. The Stockton Channel connects to the San Joaquin River and the Delta and is tidally influenced. This connection allows a substantial exchange of water and nutrients between the Stockton Channel and the San Joaquin River. In addition, water and nutrients flow from the City’s storm drain system.Water QualityMany species of algae live naturally throughout the San Joaquin Delta. Of particular concern is the blue-green algae. That’s because it makes the water look green and can cause objectionable odors. Historically, the Stockton Channel has experienced significant blue-green algae growth when the weather turns hot and winds die down. These conditions combine with nutrients in the water to promote blue-green algae growth.Bubbler SystemTo address the odor problem, the City is constructing a $1.6 million bubbler system that will mix the water in the Stockton Channel. The mixing activity will interfere with the conditions that blue-green algae need to grow. Without blue-green algae, odors will be reduced and the water color may improve.A series of forced-air diffuser lateral pipes will be anchored to the Channel bottom and spaced approximately 550 feet apart, stretching from the east end of McLeod Lake to the Interstate 5 overcrossing. Air released from small holes in the diffuser laterals will create a column of rising bubbles that cause a vertical rotation and mixing of the surrounding water.
