Procedure: During the progress of other jobs of the project, polluted waters were watched for and investigated when found. Cases of water pollution reported by sportsmen and game wardens were investigated. Findings: Lake Corpus Christi On October 1, a fish kill due to the depletion of dissolved oxygen was investigated in the upper reaches of Lake Corpus Christi, near Dinero Bridge. In addition to a large number of smallmouth buffalo which lined a portion of a slough, many channel and blue catfish, less than a pound in size, were found. The kill was not considered to be detrimental to the overall fish pop- ulation. Recommendations: This job should be continued so that future pollution cases may be investi- gated and corrective action taken to abate it. Prepared by Charles T.
