Application
of the The Lake Okeechobee Net Inflow Outlook
has been computed using 4 methods: Croley's method1, the SFWMD
empirical method2, a sub-sampling of La Nina years3 and
a sub-sampling of warm years in the Atlantic Multidecadal Oscillation (AMO)
in combination with La Nina years4. The results for Croley's
method and the SFWMD empirical method are based on the CPC
outlook. Table of the Lake Okeechobee Net
Inflow Outlooks in feet of equivalent depth. All methods are updated on a
weekly basis with observed net inflow for the current month.
See Seasonal and Multi-Seasonal tables for the classification of Lake Okeechobee Outlooks. The numeric limits on the classifications were changed effective 15 March 2005 per USACE approval. Refer to the Environmental Assessment (EA) for the Temporary Planned Deviation to Adjust Classifications of Hydrologic Indicators and Forecasts (December 2004) .
