Description S-57 is a double-barreled corrugated metal pipe (CMP) culvert, with discharge controlled by stem operated vertical lift gates. Operation of the gates is manually controlled in accordance with the seasonal operational criteria. Purpose The culvert structure is used to maintain scheduled stages in Lakes Myrtle, Preston, and Joel upstream from the structure; passes up to 30 percent of the standard project flood (SPF); and passes sufficient discharge during low-flow periods to satisfy irrigation demands downstream. Operation The culvert structure normally maintains seasonal water-control stages of from 60.0 to 6.0 ft., NGVD upstream from the structure, as shown on the regulation schedule. When the lake stage rises above schedule and above normal inflows are anticipated, releases up to design capacity of 70 cfs can be made. The gates should be opened gradually to allow tailwater stages to rise before large releases are made. During low-water periods, minimum releases will be made to satisfy irrigation demands and maintain navigation downstream. The discharge rating curve is found on Figure A-S57-. Hydraulic Design Data is found on page A-S57-. Maximum Head To meet structural and stability requirements, the maximum allowable hydrostatic head on the structure should not be allowed to exceed. ft., NGVD with a headwater elevation of 59.0 ft., NGVD, and a tailwater elevation of 56.8 ft., NGVD.

Description S-58 is a double barreled CMP culvert with discharge controlled by stem operated vertical lift gates. Operation of the gates is manually controlled in accordance with the seasonal operational criteria. Purpose The culvert structure maintains water-control stages in C-3 and Lakes Alligator, Lizzie, Coon, Center, and Trout; passes up to 30 percent of the SPF; and passes sufficient discharge during low-flow periods to meet irrigation demands downstream. Operation During floods the culvert structure is used, together with S-60, to assist in regulating and maintaining water levels of from 6.0 ft. to 64.0 ft., NGVD, in the lake upstream form the structure, as shown on the regulation schedule. The design capacity of the structure is 60 cfs. The gates should be opened gradually to allow tailwater stages to rise before large releases are made. During low-water periods, minimum releases will be made to satisfy irrigation demands and maintain navigation downstream. Discharge-Rating Curves are found on Figure A-S58-. Hydraulic Design Data is found on page A-S58-. Maximum Head To meet structural and stability requirements, the maximum allowable hydrostatic head on the structure should not be allowed to exceed.0 ft., NGVD with a headwater elevation of 64.0 ft., NGVD and a tailwater elevation of 6.0 ft., NGVD.

Description S-59 is a reinforced concrete, gated spillway with discharge controlled by a vertical lift gate. Operation of the gate is manually controlled in accordance with seasonal operational criteria. Purpose S-59 is the outlet structure for East Lake Tohopekaliga. The spillway structure normally maintains desirable water-control stages in the lake upstream from the structure; passes up to 30 percent of the SPF without exceeding desirable stages; restricts discharges during floods to that which will not cause damaging velocities or stages downstream; and passes sufficient discharge during low-flow periods to maintain stages and satisfy irrigation demands. Operation The gate in the spillway should be operated to permit water levels in East Lake Tohopekaliga to fluctuate seasonally between 55 to 58 ft., NGVD, as shown on the regulation schedule. When the lake is within one-half foot of the schedule, forecasts should be made and releases initiated to return the lake to schedule within 5 days. When the lake stage is considerably above schedule and large inflows are anticipated, releases up to design capacity of 80 cfs can be made. To insure the safety of the structure, gate settings should never exceed the limits shown on the MAGO curves and be checked frequently to insure that design capacity of the structure or C-3 downstream is not exceeded. The gate should be opened gradually to allow tailwater stages to rise before large releases are made. During low-water periods, minimum release will be made to satisfy irrigation demands and maintain navigation downstream. Downstream Weir Downstream of S-59 a sheetpile weir was constructed to influence the tailwater of the structure. The crest of the weir is elevation 50.83 ft., NGVD Maximum Head To meet structural and stability requirements, the maximum differential hydrostatic head on the structure should not be allowed to exceed 8 ft., NGVD when the headwater is below 6.8 ft., NGVD. If the headwater should ever exceed 6.8 ft., NGVD, the allowable differential head will be reduced. Kissimmee River Vol A-S59- December 005 Version Draft 4

Description S-60 is a reinforced concrete, gated spillway with discharge controlled by a stem operated, vertical lift gate. Operation of the gate is manually controlled in accordance with seasonal operational criteria. Purpose The spillway structure maintains desirable water-control stages in C-33 and Alligator Lake; passes up to 30 percent of the SPF without exceeding desirable stages; restricts discharge during floods to that which will not cause damaging velocities or stages downstream; and passes sufficient discharge during low-flow periods to maintain stages and satisfy irrigation demands downstream. Operation The spillway structure normally maintains a seasonal desirable water-control stage of 6.0 to 64.0 ft., NGVD, upstream from the structure, as shown on the regulation schedule. S-60 and S-58 both discharge from Alligator Lake, consequently discharges from both structures must be considered is establishing release schedules. When the lake is within one-half foot of schedule, forecasts should be made and releases initiated to return the lake to schedule within 5 days. When the lake stage is considerably above schedule and inflows are anticipated, releases up to design capacity of 450 cfs can be made. However, to insure the safety of the structure, gate settings should never exceed the limits shown on the MAGO Curves, and should be checked at frequent intervals to insure that the design capacity of the structure is not exceeded. The gate should be opened gradually to allow the tailwater to rise before large releases are made. During low-water periods, minimum releases will be made to satisfy irrigation demands and maintain navigation downstream. Maximum Head The maximum water level differential should not exceed seven feet with the headwater not exceeding elevation 68.0 ft., NGVD. Kissimmee River Vol A-S60- December 005 Version Draft 4
