Archived Status Reports - 2017-2018
Water samples are collected and analyzed by the Kills and Spills Team at TPWD in coordination with our federal and state partners. These samples are analyzed for Karenia brevis (red tide) and the densities of cells found are given the following designations:
- Background = Less than < 1 cell/ml
- Very Low = 1 to 10 cells/ml
- Low = 10 to 100 cells/ml
- Moderate = 100 to 1,000 cells/ml
- High = Greater than 1,000 cells/ml

There are no reports of discolored water, fish kills or respiratory irritation relating to red tide on the Texas coast.
September 20, 2018
Upper Coast (Galveston Bay and Sabine Lake): Water samples taken by TPWD on 9/17/18 show very low concentrations of red tide at Bolivar Roads near the Houston Ship Channel.
Golden Crescent (Matagorda Bay and San Antonio Bay): Water samples show low concentrations of red tide at the Jetty in Matagorda County in Matagorda Bay. Other water samples taken in Saluria Bayou near Port O’Connor in Calhoun County show low concentrations of red tide.
Coastal Bend (Aransas Bay, Corpus Christi Bay and Upper Laguna Madre: Water samples fromthe following sites were tested for red tide between 9/18/18 and 9/19/18. There have been no recent reports of respiratory irritation.
- Bob Hall Pier and Mustang Island State Park: low concentrations of red tide.
- The South Jetty in Packery Channel: very low concentrations of red tide.
- Corpus Christi Bay near Ropes Park or Swantner Park: No red tide.
Padre Island National Seashore (PINS): Very low to low concentrations of red tide were found by PINS staff at the Northern Boundary of the park, the Visitor Center, the 5 mile marker and the 10 mile marker on 9/18/18. For the most up-to-date information about conditions in this area, please contact the Padre Island National Seashore directly.
Rio Grande Valley (Lower Laguna Madre): Water samples from South Padre Island show no red tide present.
September 17, 2018
Upper Coast (Galveston Bay and Sabine Lake): No reports of red tide.
Golden Crescent (Matagorda Bay and San Antonio Bay):Water samples show low concentrations of red tide near Port O'Connor in the Matagorda Ship Channel area. No reports of respiratory irritation at this time.
Coastal Bend (Aransas Bay and Upper Laguna Madre): Water samples collected by TPWD on 9/17/18 show only background levels of red tide in Mustang Island State Park and in Packery Channel. Water samples from Bob Hall Pier show low concentration of red tide. No reports of respiratory irritation at any locations on 9/17/18.
Padre Island National Seashore (PINS): Reports of red tide and some respiratory irritation was reported last week. For the most up-to-date information about conditions in this area, please contact the Padre Island National Seashore directly.
Rio Grande Valley (Lower Laguna Madre): Water samples collected in South Padre Island show no red tide cells present.
September 12, 2018
Upper Coast (Galveston Bay and Sabine Lake): No reports of red tide.
Golden Crescent (Matagorda Bay and San Antonio Bay): No reports of red tide.
Coastal Bend (Aransas Bay and Upper Laguna Madre): Water samples collected at the UTMSI Fisheries and Mariculture Lab in Nueces County on 9/11/18 indicated low cell concentrations. Samples collected on 9/12/18 indicate moderate cell concentrations.
- TPWD staff investigated a fish kill in Packery Basin in Nueces County consisting mainly of gizzard shad. Outbound tides pushed the fish out, depositing them along the beach front. Water samples collected in the area identified a localized red tide bloom in Packery Basin. Respiratory irritation was also reported in the area. Additional water samples were collected at Bob Hall Pier and Mustang Island State Park. Although no cells were observed at those sites, slight aerosol irritation was observed at Mustang Island State Park.
Padre Island National Seashore (PINS): No reports of red tide. For the most up-to-date information about conditions in this area, please contact the Padre Island National Seashore directly.
Rio Grande Valley (Lower Laguna Madre): No reports of red tide.
August 9, 2017
Corpus Christi Bay: Water samples were collected from Corpus Christi Bay on August 8 after the persistent observation of discolored water. Samples confirmed a non-toxic algal bloom consisting of a mix of dinoflagellates. This type of bloom is not the same as the red tide blooms seen in Texas which consists of the microscopic algae known as Karenia brevis. There have been no reports of any human health effects or fish kills from this bloom.
There are no other reports of algal blooms on the Texas coast at this time.
