Powering his small boat across Dickinson Bay, Steve Hoyland Sr. worries about fish kills near the mouth of Dickinson Bayou every summer for the last six years.
Hoyland points to the depth finder to show how silt has clogged the mouth of the bayou and prevented the tide from cleansing it with oxygenated water. “We’ve got a serious problem here,” he said.
Those charged with overseeing water quality say that fish kills, where thousands of fish die for lack of oxygen in the water, are a symptom of urban encroachment on bayous like Dickinson that lace the Houston region. The urbanized area in the Dickinson Bayou watershed more than doubled between 2002 and 2008.
