PLANNING FOR DROUGHT: THE ROLE OF STATE GOVERNMENT1

ABSTRACT: Although droughts are a frequent occurrence over much of the United States, response by state and federal government has been ineffective and poorly coordinated. Recently, several states have recognized the value of drought emergency planning and have developed plans to assist them in responding more effectively to prolonged periods of water shortage. These states have created an organizational structure to coordinate the assessment and response activities of state and federal agencies. Each state's drought response plan is unique since each state's water supply and management problems, and their consequent impacts, are unique. The drought response plans developed by Colorado, South Dakota and New York are reviewed here in detail. We recommend that other states affected by frequent and severe water shortages also develop drought emergency plans. These plans will enhance state government's ability to implement effective measures in a timely manner and, ultimately, may provide added incentive for the federal government to develop the national drought response plan called for by the General Accounting Office in 1979.     

APPLICATION OF CRITICAL PATH METHOD TO WATER RESOURCES PLANNING1

ABSTRACT. The task of resource management, in this case water resources, is rapidly becoming more complex, particularly because decision making is often contingent upon various prior activities and sets of data. Comprehensive planning is required in order to prevent misallocation of resources or mismanagement in resource development. Such planning involves five general phases which are applicable to any problem faced by society: (1) problem identification; (2) formulation of alternatives; (3) evaluation of alternatives; (4) implementation; (5) review. There have been many attempts to simplify the planning process and effectively carry out these five phases. The experience of the Alberta Water Resources Division has been that the Critical Path Method is one of the most useful tools available today for planning. It involves two basic steps: (1) preparation of a network diagram which (a) identifies all the activities necessary for the completion of a project, (b) correctly sequences these activities, (c) allocates resources; and (2) mathematical computations for scheduling the activities. In other words, this approach breaks a task down into smaller units or activities for easier organization, scheduling, and performance for eventual completion of the project. This paper will illustrate the effectiveness of the Critical Path Method by discussing its application to actual water resources projects.     

THE CONTINUING EVOLUTION OF AN AUSTRALIAN WATER RESOURCES POLICY1

ABSTRACT: Australia's extremely limited water resources highlight the need for policy guidelines for management. During the 1970s, there was the gradual evolution of a national water resources policy, facilitated by a nationally agreed statement of objectives and culminating in a federal policy statement presented in 1979. However, the Australian constitution gives major responsibility for water resources to the states. Further, the federal policy statement seems to assume that each state has a water resources policy and that it accords with the nationally agreed objectives. This is not the case, and the practical management of Australia's water resources falls short of the principles set out in the policy document. The River Murray, the nation's major water resource, provides ample evidence of this fact. With very limited water resources, Australia urgently needs to reduce the disparity between principle and practice in their management.     

CHANGES IN WATER POLICY IN THE PEOPLE'S REPUBLIC OF CHINA1

ABSTRACT: Ideology has predisposed the People's Republic of China against the use of prices to allocate water. Prolonged drought in north China has made the Chinese more aware of their unfavorable water resource inventory and the expense of expanding supply. Therefore, as part of the economic liberalization commenced since the death of Mao Zedong, China has started to make more active use of pricing to regulate demand and reduce the need for supply expansion.     

DESIRED AND ACHIEVED OUTCOMES IN FEDERAL WATER RESOURCES PLANNING1

ABSTRACT Local or project level planning occurs within most federal water resources programs. Such planning involves both federal and local participants, and commonly involves a range of interest groups. It is necessary to know what goals these participants believe the planning process ought to achieve in order to design planning procedures which will meet their expectations. Social judgment analysis was used to elicit those goals for respondents who had participated in one of five different federal water resources programs, in one of five different roles. Respondents also evaluated the extent to which the planning activities in a recent project in which they had participated had actually attained the posited goals. The respondents believed that responsiveness to local problems was significantly more important than resolving conflicts or increasing public understanding. A fourth goal, achieving national objectives, was believed to be less important than the other three. No significant differences in these goal evaluations were associated with the type of program in which the respondents had participated. However, there were significant differences associated with the respondent's role in the planning process. Respondents' ratings of the effectiveness of actual planning projects varied by both program and respondent role.     

PERCEIVED WATER QUALITY AND THE VALUE OF SEASONAL HOMES1

ABSTRACT: The impact of degraded water quality on the value of seasonal homes adjacent to St. Albans Bay on Lake Champaign in northern Vermont is estimated using hedonic price functions. The Value of properties located adjacent to the bay are depressed by about 20 percent, or $4,500 on average, compared with similar nearby properties on the larger but cleaner lake. Water quality degradation resulted in decressed property values of approximately two million dollars in the area surrounding the Bay.     

IMPACT OF DROUGHT ON QUALITY OF POTENTIAL WATER SUPPLY SOURCES IN THE SANGAMON RIVER BASIN1

ABSTRACT: The analysis of stream flow and several water quality parameters in six Illinois rivers showed both deterioration and improvement in quality indicators during 1976–1977 drought. The adverse impacts were an increase of ammonia and manganese concentrations and, to a lesser degree, increased concentrations of phenol and specific conductance. At the worst point during the drought, the 12-month moving average of monthly ammonia concentration in the Sangamon River was about 620 percent higher than the antecedent value. On the other hand, average concentrations of nitrites and nitrates, total iron, and the number of coliform bacteria significantly decreased. This positive response suggests that streams which are considered unsuitable for municipal supply due to high levels of these quality indicators may be used as emergency sources during droughts.     

CAPITAL COSTS OF RURAL WATER SYSTEMS: AN EMPIRICAL APPROACH1

ABSTRACT: In the last two decades the federal government has provided substantial capital to construct rural water distribution systems. Loans at subsidized interest rates and front-end grants through the Farmers Home Administration have been the main source of this capital. Recent federal policy redirections have reduced substantially the availability of grants and subsidized loans. Because of design and material differences, capital cost estimates from urban systems are not uniformly applicable to rural water services. This study presents an econometric analysis of capital costs, using Illinois rural water system construction contract bids. Cost equations by systems components representing 90 percent of capital costs are estimated. The type of information developed here can be used in initial planning and optimization design models contributing to the efficient provision of rural water services.     

STATE WATER PLANNING: A FORUM FOR PROACTWELY RESOLVING WATER POLICY DISPUTES1

ABSTRACT: In the arid West, the development and implementation of water policy often results in disputes among water users, resource managers, and policy makers. Although significant attempts have been made to improve public involvement and dispute resolution in water resources planning, the traditional planning process has not historically played this role for a variety of reasons. Water resources planning can become a forum for proactively resolving water policy disputes by employing the principles of environmental dispute resolution. The purpose of this article is to explore the role of collaborative, consensus-building planning processes in resolving water policy disputes. The Montana State Water Plan is evaluated as an example of such a process, and a model state water planning process is outlined.     

DROUGHT PLANNING: A PROCESS FOR STATE GOVERNMENT1

ABSTRACT: Drought has been a prevalent feature of the American landscape during the latter part of the 1980s, producing serious socioeconomic and environmental consequences. These recent experiences with drought have renewed concern about the inadequacy of federal and state contingency planning efforts and the lack of coordination for assessment and response efforts between these levels of government. This paper presents the results of research aimed at facilitating the preparation of drought contingency plans by state government in conjunction with a state's overall water management planning activity. The ten-step drought plan development process reported is intended to improve mitigation efforts through more timely, effective, and efficient assessment and response activities. Officials in appropriate state agencies should examine the proposed framework and alter it to best address drought-related concerns, adding or deleting elements as necessary.     

THE HYDROLOGIC ENGINEERING CENTER EXPERIENCE IN NONSTRUCTURAL PLANNING1

ABSTRACT: The Hydrologic Engineering Center, Corps of Engineers, has been engaged in research, training, and project assistance in non-structural flood control planning for Corps offices across the United States since 1975. Lessons learned from this experience deal with the role of nonstructural measures in flood plain management, the role of creativity in analysis, the role of analysis, and tools for analysis. The role of nonstructural measures in flood control planning depends upon the scale of the problem, the nature of the measure, the degree of protection desired, and whether damage is to existing or future property. An earnest seeking for nonstructural opportunities, a field presence for their formulation, and compatbility with local infrastructure plans are prerequisite to creative use of nonstructural measures. Analysis is a necessary complement of creativity. Several tools for nonstructural analysis have been developed and applied to flood problems involving several hundred and several thousand structures.     

THE ENHANCED ROLE OF WATER CONSERVATION IN THE COST-BENEFIT ANALYSIS OF WATER PROJECTS1

The concept of water conservation has increased in importance because of revisions in the rules and procedures for performing cost-benefit analyses of federal water projects. These revisions include a requirement that nonstructural and water conservation measures be incorporated into economic assessments of projects. Project analyses will now proceed as if water supplies were allocated “most effectively,” that is, to their highest valued uses. A related requirement provides that the net benefits of any project should now be valued using willingness to pay measures. A specific cost-benefit methodology accommodating the revisions is constructed and discussed. Informational requirements for applying this methodology are identified. In addition to being consistent with federal mandates, this technique offers important advantages over the traditional “requirements” approach to water supply planning.     

STATE LEGISLATIVE RESPONSE TO THE CENTRAL ARIZONA PROJECT1

This research deals with the manner in which the Arizona Legislature dealt with the issue of the Central Arizona Project. Due to the massive costs and impact, the Central Arizona Project was handled by the Legislature in a nonroutinized manner. There was no Legislative precedent for dealing with such a major public work project. Given the Legislature's annual program concerns and priorities, it is neither structurally nor psychologically geared to respond to the Central Arizona Project in terms of placing it within an agenda of priorities even for discussion.     

IMPACT ON RESIDENTIAL WATER CONSUMPTION OF AN INCREASING RATE STRUCTURE1

ABSTRACT: A two-step procedure is used to estimate the impact of an increasing rate structure on residential water use. An error components regression procedure is used to estimate demand relationships for a period prior to the rate change. Water use is predicted for the post rate change period, assuming that the rate structure was not changed. Comparison of actual with predicted use indicate that water use declined as a result of the imposition of the increasing rate structure.     

INTEGRATING SOCIAL ANALYSIS INTO WATER RESOURCES PLANNING: SOME EMERGING TRENDS IN THE CORPS OF ENGINEERS1

ABSTRACT: While federal water resources laws and regulations require social analysis, no one workable formula exists for integrating it into water resources planning. Two primary problems in integrating social analysis into planning are examined; making trade-offs between policy acceptability and theoretical competence, and managing social analysis in planning. For illustration, the article builds on emerging trends within the U.S. Army Corps of Engineers. It concludes by observing that creative application of social theory to policy problems along with innovative data gathering techniques are the primary routes to managing these problems.     

TECHNIQUES FOR DETECTING TRENDS IN LAKE WATER QUALITY1

ABSTRACT: With the advent of standards and criteria for water quality variables, there has been an increasing concern about the changes of these variables over time. Thus, sound statistical methods for determining the presence or absence of trends are needed. A Trend Detection Method is presented that provides: 1) Hypothesis Formulation - statement of the problem to be tested, 2) Data Preparation - selection of water quality variable and data, 3) Data Analysis - exploratory data analysis techniques, and 4) Statistical Tests - tests for detecting trends. The method is utilized in a stepwise fashion and is presented in a nonstatistical manner to allow use by those not well versed in statistical theory. While the emphasis herein is on lakes, the method may be adopted easily to other water bodies.     

IMPACT OF WATER CUTBACK ON SUGARCANE PRODUCTION IN THE FLORIDA EVERGLADES1

ABSTRACT: Sugarcane (Saccharum spp.) was planted in six lysimeters containing Pahokee muck (Lithic Mediaprist) where water tables were maintained at 30, 60, and 90 cm depths. The main objective was to study the impact of a 40 percent water cutback (108 mm) on sugarcane production during the period near the end of the dry season (i.e., May). The water cutback treatment was simulated through manipulation of water table depth. Due to the high available water capacity of the muck soil and selection of a sugarcane cultivar ‘CP63-588’ (which has a high tolerance of water table fluctuations), the sugarcane growth, and the yields of sugarcane biomass and sugar were not significantly different as a result of the treatments with and without 40 percent water cutback during a period of two months. This result is in good agreement with the 1981 cane yield in the Everglades Agricultural Area where a 35 percent water cutback was imposed during the 1981 drought.     

WATER SUPPLY FORECASTING IN REAL-TIME1

ABSTRACT: A strategy is developed for making seasonal water supply forecasts in real time. It links the traditional regression based forecasting techniques to real-time data acquired by systems such as the Soil Conservation Service SNOTEL and the U.S. Bureau of Reclamation Hydromet networks. The concept is based on interpolating between the forecast values obtained by using real-time data in the forecast equations that bracket the real time. Different interpolation procedures were examined and the procedure for calculating confidence intervals about the forecast estimates is developed. The entire conceptual procedure is demonstrated using data from the Reynolds Creek, Idaho, experimental watershed maintained by the USDA-ARS Northwest Watershed Research Center in Boise, Idaho.     

NATIONWIDE ASSESSMENT OF URBAN RUNOFF IMPACT ON RECEIVING WATER QUALITY1

ABSTRACT: Urban stormwater runoff has been recognized as a potential major contributor of pollution to receiving waters. However the projected high costs of control have prompted an examination of the extent to which these impacts have been documented. A nationwide search was conducted for case studies demonstrating a cause-effect linkage between urban runoff and impairment of beneficial uses in receiving waters. The results indicate that numerous definitions of “impacts” are being used and that few substantive data exist to support many of these allegations. Results of a preliminary impact assessment are presented for the 248 urbanized areas of the United States. Then, the results of more recent efforts to assess these impacts in several case studies are described. This assessment demonstrates the critical need for additional short-term and long-term sampling programs.     

STATE WATER CONSERVATION STRATEGIES AND ACTIVITIES1

States have the potential to play a major role in moving water conservation from conferences and reports that identify its advantages to actual practice. The research identifies four generic “strategies” that categorize the states' approaches toward conservation and reports on the states' current conservation activities. The four strategies are: reliance on agricultural advisors, leverage incentives, performance standards, and mandatory actions. Four levels of state conservation activity exist. California and Florida maintain the most extensive programs; Arizona, Massachusetts, New Jersey, North Carolina, and Oklahoma also have numerous programs but significantly lower staff commitments; eight additional states maintain more modest conservation effotts. Elsewhere, state directed conservation actions remain minimal and limited to those provided as agricultural advice. The study found support for water conservation the norm among water supply planners.
