Geographic Display Introduction

The geographic display is an interactive map showing economic and environmental results for the candidate plans and Plan E (a reference plan) relative to Plan 1958DD. The geographic display allows the user to view the impact that the regulation plans have on a particular area of the basin for the various performance indicators. The economic results are provided in average annual ($ U.S. million) with positive values improving results relative to Plan 1958DD and negative numbers causing increased harm. The environmental results are ratios with values greater than 1 improving on Plan 1958DD performance and values less than 1 decreasing performance. The economic results are based on the full 50,000-year stochastic supply sequence and the environmental results use the historical supply sequence.
