East Matagorda Estuary
The East Matagorda estuary covers an area ofabout 56 square miles (145 square kilometers) and
consists of East Matagorda Bay, part of the IntracoastalWaterway, the tidal reaches of Caney Creek and LiveOak Bayou, and the tidal part of small tributaries(Figure 4). The maximum water depth at mlw is 5 feet(1.5 metersl in East Matagorda Bay and about 15 feet(4.6 meters) in the Intracoastal Waterway.
Water-quality data (Table 3) were collected duringSeptember 1972 and May 1973.
The changes in line numbers to facilitate storage inthe Texas Water Oriented Data Bank and to provideopportunity to coordinate data-collection sites among allagencies are shown below. New line numbers are used inTable 3 and Figure 4.

SELECTED HYDROLOGIC RECORDS
Climatological Records
The climate of a region plays a great role inestuarine water quality. The types of climatological dataavailable for a 60-mile- 197-kilometer-) wide band alongthe Texas coast are shown on Figure 11.
Tabulations of daily precipitation, temperature,and other data are published monthly, and monthlysummaries are published annually by the EnvironmentalScience Services Administration in the series titledClimatological Data-Texas. For the period 1931-60,monthly and annual data are summarized in two U.S.Weather Bureau publications (1958, 1965).
