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) . The recommended methods and values for use in the WSE
