Estuary Science Exchange

Estuary Science Exchange Logo

The Texas Water Development Board is pleased to announce the speakers for the kickoff to the Estuary Science Exchange - a Texas-wide forum for sharing estuarine science among professionals working on coastal issues. Following each presentation there will be time available for discussion.

Generally, the forum aims to:

  1. Encourage collaboration and working relationships among participants
  2. Serve as a forum for participants to:
    1. Share research findings regarding natural events, changing environments, and ongoing issues
    2. Introduce new projects or provide updates on ongoing activities
    3. Discuss research methodologies or estuarine management tools for Texas estuaries

Reach out to the Estuary Science Exchange team to be added to the distribution list, questions, comments, or assistance.

Dr. Quinn McColly

Dr. Quinn McCollyThe Texas Water Development Board is pleased to announce that our next Estuary Science Exchange will feature Dr. Quinn McColly from 10:00 – 11:30 am CST on September 1, 2022. Dr. McColly will discuss his ongoing work at the Texas Water Trade where he leads the organization’s programs aimed at generating voluntary transactions to secure environmental water while also meeting agricultural, industrial, and municipal needs. The talk will be held virtually through Microsoft Teams and be followed by an opportunity for questions and discussion.

Dr. Quinn McColly has a unique background that combines practical market experience with academic research. Dr. McColly earned his Ph.D. in Coastal and Marine System Science at the Harte Research Institute for Gulf of Mexico Studies at Texas A&M University- Corpus Christi where he wrote his dissertation Market Mechanisms and the Efficient Allocation of Water. He arrived at the Harte Research Institute after a long stint in the world of finance, working as a floor trader on the Chicago Stock Exchange for a decade before moving laterally into an advisory position in private wealth management. He earned his master’s degree at TAMU-CC in Environmental Science after defending his thesis Evaluating the Interest of Voluntary Buyers in an Ecosystem Services Exchange.

Please register on Eventbrite to attend to this presentation.

Don’t miss this opportunity to discuss how water is being allocated for our estuaries during such a critical time!

A Brief History of Freshwater Inflow Policies and Studies, Dr. Paul Montagna

The Hydro-Illogical CycleAbstract: Water development projects are constructed for human benefit, but always alter hydrology, thus altering environmental flow regimes, particularly for estuaries that are the receiving waters at the end of river courses. After the eight-year drought in the 1950s, which resulted in hypersaline estuaries, fish kills, loss of blue crabs and white shrimp, and invasions by stenohaline species, the Texas State Legislature passed a series of acts since 1975 requiring comprehensive studies of the effects of freshwater inflows on bays and estuaries. On the policy side, management has moved from a species-based approach to an ecosystem-based approach. On the science side, many different tools and approaches have been developed to define inflow needs. We are now 10 years past the initial statewide environmental flow standards being established in 2011-2013, so we are at the beginning of a new era of adaptive management.

About the Speaker: Paul Montagna, Ph.D. is the Harte Research institute Chair for HydroEcology at Texas A&M University-Corpus Christi. He has been studying inflow needs of Texas bays and estuaries since 1986. He is currently the Editor-in-Chief for the journal Estuaries and Coasts.

Coastal Management Projects and Relationship to Freshwater Inflows, David Buzan

Coastal water with reedsAbstract: Freese and Nichols, Inc. (FNI) is working on different projects for the Texas General Land Office involving construction of habitat and habitat protection features in estuarine environments. A recently completed project involved the siting and design of oyster reefs to be placed in the Galveston Bay system. Suitable salinities for oysters, changes in freshwater inflow, and tidal exchange were considered in identifying appropriate locations for construction of oyster habitat. Trinity Bay was considered but recent years of high freshwater inflow reduced oyster productivity in that system. West Bay was not considered because in recent decades freshwater inflows have not been consistent enough to sustain healthy oyster reefs, decimated by dermo in higher salinity environments. East Bay was selected for oyster reef construction sites because of the relatively stable salinity regimes. However, the closure of Rollover Pass to tidal exchange has raised unanswered questions about the long-term salinity patterns in East Bay and their suitability for oysters.

A current project involves protecting and restoring the mouth of Carancahua Bay, a secondary bay of the Matagorda Bay system. Erosion and shoreline breaches along Redfish Lake and Salt Lake, within the Carancahua Bay system, have resulted in ecosystem change threatening marshes. Sea level rise, changes in sediment transport, and tidal prism will continue to impact this system. Questions arise whether or not there will be adequate sediment accretion to support existing marshes and prevent marsh drowning, and whether or not there be adequate freshwater inflow in the future to maintain this ecosystem?

About the Speaker: David Buzan is a Biologist with Freese and Nichols, Inc. in Austin who has worked on water quality and quantity issues in Texas since 1978.
