83 4 Reconsidering Available Storage Options The planning framework, boundary conditions, and planning constraints that are found in the Restoration Plan are themselves the result of a process of adaptation to the interests and concerns of the myriad stakeholders in south Florida. The constraints and conditions that emerged during the initial stages of planning were necessary to allow the project to move forward.

Reconsidering Available Storage Options 85 compared with any of the Great Lakes. It also has been the center of many controversies in recent decades concerning its function in the larger system and the most appropriate strategies for its management (e.g., Steinman et al., 2001; Havens, 2002; Bachmann et al., 2003)

86 Re-Engineering Water Storage in the Everglades: Risks and Opportunities The hydrology and morphometry of Lake Okeechobee and its drainage basin have been modified greatly over the past 125 years, and the current system bears little resemblance to conditions that existed when early explorers visited the region in the early and mid-nineteenth century (Tebeau, 1971, 1974)

Reconsidering Available Storage Options 87 By early 1883, the natural flood channel toward the Caloosahatchee River had been widened to a shallow canal (Leach et al., 1971)

Reconsidering Available Storage Options 89 The former issue is complicated by the spatial and temporal variability of nutrient levels in this large lake; at different times and locations, either phosphorus or nitrogen may be the potentially limiting nutrient for planktonic primary production (e.g., Brezonik et al., 1979) , but light conditions usually are the actual limiting factor (Phlips et al., 1997; Bachmann et al., 2003)

92 Re-Engineering Water Storage in the Everglades: Risks and Opportunities Given the above comments and the possibility that other storage options (e.g., ASR) may not provide the amounts of water needed to fulfill the restoration plan, the committee judges that it would be prudent to revisit the question of whether Lake Okeechobee can provide some of the sought-for water storage.
