(a) The Brazos River and its associated tributaries
and bay and estuary system and the San Bernard River and its associated
tributaries are healthy and sound ecological environments.
(b) The commission finds that these sound ecological
environments can best be maintained by a set of flow standards that
implement a schedule of flow quantities that contain subsistence flow,
base flow, and high flow pulses at defined measurement points. Minimum
flow levels for these components will vary by season and by year since
the amount of precipitation and, therefore, whether a system is in
dry, average, or wet base flow conditions, will vary from year to
year and within a year from season to season, and the number of pulses
protected will also vary with the amount of precipitation and hydrologic
conditions.
