     The Guadalupe-Blanco River Authority (GBRA) treated the Guadalupe River with Nautique the week of September 15-19, to control the aquatic invasive plant hydrilla. The plant, whose growth had began affecting the accuracy of flow-gauges located downstream, had prompted the introduction of triploid grass carp in 2013; “The carp are still doing their job,” said Debbie Magin, the GBRA Director of Water Quality Services, “but the hydrilla is spreading much more rapidly now because of low river flows.” More information on the project is available through the link below.
