PORT MAYACA, Fla. (CBS12) — Army Corps of Engineers (USACE) Jacksonville District will execute a temporary, minor deviation to the Lake Okeechobee Regulation Schedule April 20-21 as part of the ongoing study by the South Florida Water Management District (SFWMD) and U.S. Geological Survey (USGS) to find ways to indirectly measure sediment and nutrients transported from the lake to the estuaries. The deviation will allow up to 5,000 cubic feet per second (cfs) flow from structures for short periods of time for up to 8 hours on April 20 at the Moore Haven Lock and Dam (S-77) and April 21 at the Port Mayaca Lock and Dam (S-308). USACE executed a similar deviation in February to support the same study and expects to do so again in May. This study will help develop a better understanding of how different release schedules may influence nutrient/sediment loading to the estuaries.
