9. Characteristics: Riparian Water Regulations Riparian Water Regulation: Overall Goals • Riparian water regulation should serve as a water allocation instrument in times of drought. • Riparian water regulation should provide a mechanism for the users to reallocate water among themselves in ways that are mutually beneficial to them. • Riparian water regulation should meet the needs of society to maintain minimum streamflows (i.e. aquatic habitats) and lake and aquifer levels in times of normal run-off as well as during low-flow periods.

10. Characteristics: Riparian Water Regulations Objectives: Used to evaluate a Riparian Water Withdrawal Regulatory Program • Ease and Effectiveness of Implementation, Administration, and Enforcement • Equity • Effectiveness and Sustainability in Protecting Water Resources • Economic Efficiency • Robustness (Insensitivity to Errors) • Political and Legal Feasibility

11. Characteristics: Riparian Water Regulations Guidelines: Developing A Water Withdrawal Regulatory Program • Within any area where it intends to control water withdrawals, the Agency should require withdrawal permits by all users above a critical size regardless of their type of use.The Agency may exempt small users from the permitting requirement. It may be helpful to put a cap on the amount of the exempted withdrawal. • Permits should be defined in terms of both withdrawal and consumption. Any modification of a permit should be subject to Agency review and approval. • The Agency should establish a procedure for estimating return flows and should use this procedure in its planning. • Revenues should be generated through administrative fees assessed uniformly of each applicant. Non-payment of administrative fees for a specified period of time should result in a forfeiture of permits. • The Agency should require measuring devices to be installed on all facilities for withdrawing water from natural watercourses. It should either monitor those withdrawals itself or require a self-reporting system by the users. In the latter case, the Agency should establish an audit system, a citizen reporting system, and unannounced inspections to ensure a high degree of compliance.

12. Characteristics: Riparian Water Regulations Guidelines: Bases for Defining Permits • The allowable withdrawal or consumption by a given user should be based on a system of sharing and should be expressed as a continuous function of local streamflow measured at a nearby stream gauge. The continuous function may take into account of the priority of the user with respect to other users or types of use. • Under water shortage, an appropriate quantity of water should be allocated first for the essential needs of users. Once these needs have been satisfied, further flow should be allocated according to the chosen basis of permit definition with all sectors having equal priority. The highest priority allocations should not be as large as the total normal allocation same user, but should be only sufficient to serve critical needs. For domestic use, the highest priority allocation should be no more than 400 liters per capita per day. (105 gallons per capita per day)

13. Characteristics: Riparian Water Regulations Guidelines: Bases for Defining Permits (continued) • The purpose of a permitting system is to solve problems of human use and impacts on water resources, not to perpetuate them. While existing users may be given priority over new ones, they should receive permits according to one of the following bases: Riparian size Operational size Historical use Ad Hoc methods • Additional Issues: Duration of Permits and How to Accommodate Newcomers • The Agency should allow transfers of permits among users to the extent that such transfers are determined by the Agency not to damage the aquatic environment or third parties. • To the extent possible, within the limitations of data accuracy, total withdrawals from aquifers should be set to maintain aquifer levels i.e. prevent ground water mining.

14. Characteristics: Riparian Water Regulations Resource Assessment and Maintenance: Guidelines • The Agency should set minimum streamflow standards that must be maintained at particular stream gauges with a specification of how those minimum flows may vary throughout the year or by temperature. • The Agency should set target minimum aquifer levels that must be maintained at particular observation wells with a specification of how those levels may vary throughout the year. • The Agency should set minimum lake levels that must be maintained at particular observation points with a specification of how those levels may vary throughout the year.

15. Examples • Secretary of Interior reduces the allocation of Colorado River water to California by 260 billion gallons/year (NY Times 2003) • Cypress Groves, Wetlands, Springs, and Lakes in Florida (Glennon 2002) Water Follies-Tampa Bay’s Avarice • Legislative Bill: State of Florida (HB 1069, Florida House of Representatives (Representative David Russell, Brooksville, FL) Response of the Natural Resources Committee of the House of Representatives in the State of Florida

16. Secretary of Interior reduces the allocation of Colorado River water to California by 260 billion gallons/year (NY Times 2003) • Agreement among the seven western states entitled to withdraw water from the Colorado River requires California to reduce its use of water above its specified allocation • Imperial Irrigation District fails to reach agreement with City of San Diego to sell 200,000 acre-feet of water/yr. This volume of water is 7% of the total the 400 farmers in the irrigation district receive from the Colorado River each year • Had the agreement gone forward, preliminary calculations indicate that the Imperial Irrigation District would have netted $47 million/year. • Secretary Norton orders California’s withdrawals from the Colorado River to be reduced by 650,000 acre-feet/yr effective January 1, 2003

17. Cypress Groves, Wetlands, Springs, and Lakes in Florida (Glennon 2002) Water Follies-Tampa Bay’s Avarice • Florida receives 54 inches of rain/yr: yet has significant water problems • Excessive population growth in Southwest Florida Water Management District (SWIFTMUD): Tampa Bay/St. Petersburg (TB/SP) Metro Region • Tampa Bay Water (TBW) supplies TB/SP: Groundwater primary source 225 mgd 1996-projected water need for year 2020 is 425 mgd • Groundwater withdrawal rates by TBW have caused significant adverse impacts on both groundwater and surface water in three counties • TBW has a 25 mgd desalinization plant online: requires 30 megawatts of energy to produce 100 gallons/capita/day for 250,000 people • TBW has identified additional groundwater sources in a fourth county further away from TB/SP. • Political opposition to this possibility has been swift, intense, and blunt • Groundwater mining has taken place: not sustainable

18. Legislative Bill: State of Florida (HB 1069, Florida House of Representatives Selected Provisions • Requiring local governments to include projected water use in comprehensive plans • Providing for a water conservation guidance manual • Providing for a public workshop on the development of regional water supply plans that include consideration of population projections • Providing for a list of water source options in regional water supply plans including conservation measures in regional water supply plan • Allow for the limited transfer of water from one use to another under specified conditions • Providing for the development of groundwater by regional water supply authorities and providing for the approval thereof • Providing for a Peace River Comprehensive Study • Requiring water management districts to develop landscape irrigation and xeriscape design standards • Providing for the use of reclaimed waters

19. Observations: Lessons for the Future • The distribution, abundance, quality and biodiversity of freshwater resources are essential and vital for the sustenance of life on earth • The technology to provide for potable freshwater at any location and at any time is limited • Human use of freshwater resources needs to be undertaken with care and utilizing conservation measures to ensure the most effective and efficient use of the freshwater resource • Permit procedures for the withdrawal of both surface water and groundwater as well as for the consumptive use of these waters need to be implemented • The development of sustainable water resource systems requires a comprehensive interdisciplinary systems analysis. • Sustainable water resource systems guidelines exist that are multi-disciplinary and enable responsible parties to carryout the needed planning, implementation, and maintenance of such systems • In Florida, the Committee on Natural Resources of the House of Representatives has a strong commitment to creating an institutional framework for the State to confront and appropriately address the provision of sustainable water resources • Sustainable water resources are essential for our life on earth; sound business practice requires taking a longer-term perspective on the sustainable use and protection of water sources at present and into the future.
