| (a) A management plan shall contain, unless explained
as not applicable, the following elements:
(1) Management goals:
(A) providing the most efficient use of groundwater;
(B) controlling and preventing waste of groundwater;
(C) controlling and preventing subsidence;
(D) addressing conjunctive surface water management
issues;
(E) addressing natural resource issues which impact
the use and availability of groundwater, and which are impacted by
the use of groundwater;
(F) addressing drought conditions;
(G) addressing conservation, recharge enhancement,
rainwater harvesting, precipitation enhancement and brush control,
where appropriate and cost-effective; and
(H) addressing the desired future conditions established
pursuant to Texas Water Code §36.108;
(2) Management objectives that the district will use
to achieve the management goals in paragraph (1) of this subsection.
Management objectives are specific and time-based statements of future
outcomes, each linked to a management goal. Each future outcome must
be the result of actions that can be taken by the district during
the five years following the effective date of the adopted management
plan;
(3) Performance standards for each management objective.
Performance standards are indicators or measures used to evaluate
the effectiveness and efficiency of district activities. Evaluation
of the effectiveness of district activities measures the performance
of the district. Evaluation of the efficiency of district activities
measures how well district resources are used to produce an output,
such as the amount of resources devoted for each management action;
(4) Details of how the district will manage groundwater
supplies in the district, including a methodology by which the district
will track its progress in achieving its management goals. At least
one goal must be tracked on an annual basis; however, other goals
may be defined and tracked over a longer time period as appropriate;
and
(5) Estimates of the following:
(A) modeled available groundwater in the district as
provided by the executive administrator based on the desired future
condition established under Texas Water Code §36.108;
(B) the amount of groundwater being used within the
district on an annual basis taken from either the water use survey
data provided by the executive administrator or the district's own
estimate;
(C) the annual amount of recharge from precipitation,
if any, to the groundwater resources within the district as provided
by the executive administrator;
(D) for each aquifer, the annual volume of water that
discharges from the aquifer to springs and any surface water bodies,
including lakes, streams, and rivers as provided by the executive
administrator;
(E) the annual volume of flow into and out of the district
within each aquifer and between aquifers in the district, if a groundwater
availability model is available from the executive administrator;
(F) the projected surface water supply in the district
according to the most recently adopted state water plan; and
(G) the projected water demand for water in the district
according to the most recently adopted state water plan.
(b) The management goals, performance standards and
management objectives required in subsection (a)(1), (2), and (3)
of this section must be consistent with the established desired future
conditions of the district's groundwater management area(s).
(c) Each district must use the groundwater availability
modeling information provided by the executive administrator in conjunction
with available site-specific information provided by the district
when developing the estimates required in subsection (a)(5) of this
section.
