Arroyo staff have supported The Brazos River Authority (BRA) with instream flow studies as part of a Water Management Plan (WMP) under the current draft of the System Operation Permit. Arroyo staff have worked with the BRA and other state environmental resource agencies to design and execute an effective work plan that identifies necessary environmental studies to be conducted over the next three to ten years. The studies in the Work Plan will allow development and submittal of a WMP to Texas resource agencies. Initial tasks include preliminary hydrology and biology field studies and analysis. This field effort was conducted in support of BRA initiatives to collect baseline data on current conditions of the Brazos River.
Arroyo staff continue to assist Trinity River Authority (TRA) staff with work on the Trinity River. This work supports the Senate Bill 2 Texas Instream Flow Program. This involves data collection and sampling for the long term channel migration and stability of the Trinity River, and the Trinity River channel’s direct effect on Lake Livingston. This study also includes classification of instream meso habitat and the establishment of long term monitoring cross sections at various locations within the Trinity River.
