Coastal Hydrographic and Meteorological Study, 1969-1970
MetadataShow full item record
Hydrographic and meteorlogical data collected in the field and taken from publications are presented in the report. River flow measurements were available for six major rivers entering coastal bay areas in 1969 and three in 1970. Measurements were available from January through September. Commercial landings indicate shrimp and crabs were taken in larger numbers in areas of higher rainfall and lower salinities. Finfish were taken in larger numbers in the Laguna Madre where rainfall was lower and salinities were relatively higher. Habitat modifications included routine maintenance dredging of the Intracoastal Waterway and existing channels, dredging of new channels, drilling oil wells, placement of pipelines, bulkheading and filling, mud shell dredging.
