### Lake Okeechobee Regulation Schedule

Under LOSOM "we" should see:

* Reduced low flow discharges to CRE

* Reduced stressful, and damaging discharges (from Lake) to CRE

* Increased optimal discharges to CRE

* .red[Increased extreme discharges to CRE]

* .red[Higher Lakes stages more frequently]

* Increased flows south

* Reduced regulatory volumes to CRE, SLE, and LWL.

### Application of Hydrologic Restoration Goals for a Large Subtropical Lake *(In Prep.)*

.pull-left[
Based on methodology of Havens (2002).

Lake stage is a major driver in Lake ecology (see Conceptual Ecological Model).
.small[
* Extreme high lake stage (>5.2 m/17 Ft NGVD29)

* Moderate high lake stage (>4.9 m/16 Ft NGVD29) > 90 days

* Moderate low lake stage (<3.3 m/11 Ft NGVD29) > 90 days

* Extreme low lake stage (<3.0 m/10 Ft NGVD29)

* Spring/SNKI nest period recession
  * March 1 - June 15
  * weekly recession rate between -0.05 and 0.05 Ft/wk (0.02 m/wk) for more than 1/4th of nesting period.

* Events per decade

* PA25 has higher Extreme & Moderate high stage events .small[(see Extreme Event Analysis [slide](#LOK5))] lowering the score.

* LOSOM is not a restoration plan but should take into account ecology of the system.

* Benefits to other parts of the system is balanced on the back of the Lake
