Impact
Construction of the Lake Chabot dam is considered to be one of the main causes of the formation of Arrowhead Marsh in San Leandro Bay, at the mouth of San Leandro Creek near the Oakland International Airport. Coastal surveys show the marsh appearing sometime between 1855 and 1895, though logging of the San Antonio Forest may have also played a role. Aside from sedimentation caused by normal earth-fill dam construction, much of the dam's clay core and soil overburden were washed away in a storm during construction in either 1874 or 1875.
Today, Arrowhead Marsh is one of the last remaining wetlands in the East Bay, and part of Martin Luther King Jr. Regional Shoreline, while nearly all of the surrounding historic marsh has been covered with industrial development.

“If the federal government had been around when the Creator was putting His hand to this state, Indiana wouldn’t be here. It’d still be waiting for an environmental impact statement.”

“The question confronting the Church today is not any longer whether the man in the street can grasp a religious message, but how to employ the communications media so as to let him have the full impact of the Gospel message.”
—Pope John Paul II (b. 1920)
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
