Plans Across the USA
Groundwater management plans are an important tool for guiding policies and actions that help to achieve and preserve the desired state of the aquifer, while meeting economic, social and environmental goals. Groundwater management plans set out a vision, specify concrete goals and objectives, and identify polices that will collectively serve to achieve these goals and objectives. Effective groundwater planning requires knowledge of the groundwater system and an ability predict, determine the effects of, monitor, and control the human actions that impact the groundwater system.
In the USA, the management of groundwater primarily falls under state jurisdiction, as such, the legal and regulatory environment for groundwater management planning varies substantially. In some states, a state-level agency is responsible for the development of groundwater management plans [top-down]. In other states, legislative or administrative laws designate regional or local-level agencies responsibility for the formation of groundwater management agencies and groundwater management plans. States may legally require those agencies produce plans [bottom-up mandatory] or states may instead provide an enabling framework that encourages and incentivizes but does not require those agencies to develop groundwater management plans [bottom-up voluntary]. Incentives may be financial (including eligibility for grants, loans, or assistance), technical support, or involve the granting/devolution of regulatory powers to those who develop plans. Lastly, some states include groundwater management in state water plans or integrated plans rather than producing independent groundwater management plans.

Top-down: GWMPs are developed at the state level by the Arizona Department of Water Resources for five Active Management Areas (AMAs). Plans are developed every 10 years over the course of a 50 year planning period. Each new plan must be more rigorous than the last in terms of proposing new conservation and management requirements for agricultural, residential, and industrial use.

GWMPs for both groundwater quantity and quality are used in Idaho.
Quantity:
Bottom-up, mandatory: GWMPs related to groundwater quantity are required to be developed in areas that have been designated as "critical groundwater areas" by the Department of Water Resources. Local advisory committees then are responsible for developing the plans.
The items marked below in green are the science and metric setting requirements for groundwater management plans in the state. The items below marked in grey are not required to be included in GWMPs.
Reference: Idaho Statutes, Title 42, Chapter 2, Section 42-233a
Quality:
Bottom-up, voluntary: GWMPs related to groundwater quality are voluntarily developed at the local level, typically by a stakeholder group put together by the Department of Environmental Quality. The stakeholder groups are formed after the DEQ identifies high levels of nitrates in an area. Development and implementation of a GWMP by the stakeholder group is completely voluntary.
There are no content requirements for the voluntary groundwater quality management plans. According to the Department of Environmental Quality, the plans generally should identify what needs to be protected, what degree of protection is required, and how the stated protection will be accomplished.

Formal groundwater plans are not used. Groundwater may be addressed through other water resources planning documents (state water plan, integrated management plans, or basin management plans).Kansas
Bottom-up, mandatory: The state has designated five separate Groundwater Management Districts (GMD) each of which is required to develop a GWMP; GMDs are located in areas of the state that rely on withdrawals from the Ogallala aquifer, and the rest of the state is covered by the Water Appropriation Act.
The items below marked in yellow are considered by the state engineer when reviewing a plan prior to approval.
There are no concrete requirements for plan contents. K.S.A. states that the state engineer will only review if a plan proposes clear geographic boundaries, pertains to an area wholly within the groundwater management district, proposes goals and corrective control provisions to meet stated goals, gives due consideration to water users who have already implemented reductions in water use resulting in voluntary conservation measures, includes a compliance monitoring and enforcement element, and is consistent with state law. If the engineer deems the plan satisfactory in regard to those items, then the district may implement the plan. Otherwise, there are no specific content requirements.

GWMPs are currently trials. There are no formal requirements or recommendations for what should be included in the plans.

Bottom-up, voluntary: Once the State Engineer has designated a basin as a "critical management area," local groups can develop and submit GWMPs to the state engineer for approval. If a GWMP is not approved within 10 years of the CMA designation, then withdrawals in the basin must conform to priority water rights.
The items below marked in yellow are considered by the state engineer when reviewing a plan prior to approval.
Because plans are developed voluntarily, the only requirement is for the plans to work towards removing the CMA designation. However, when the State Engineer is determining if a GWMP should be approved there is a list of items that they may consider, but the items are not necessarily required to be in the GWMP.

Bottom-up, mandatory: Development of groundwater action plans is required in areas designated as a Groundwater Management Areas (GWMAs) by the state Areas are designated as GWMAs when there is widespread contamination in a basin. The local committees and interested parties work with state agencies to develop the content of the action plan.
There are no specified requirements for groundwater action plans. The only aspect of planning that is mentioned in the legal text is the formation of the GWMA and the respective groups that would work on the development of an action plan.
