WEATHER AND WATER STAGE

1. The below-stated water fluctuations are for informational purposes only and are not to be utilized in conjunction with any contract-related hydrographic surveying purposes as noted on the control drawing(s) of the contract plans. All elevations in this Section 00 33 50 are in feet, National Geodetic Vertical Datum of 1929 (feet, NGVD).

2. The Kissimmee River Restoration (KRR) Contract 12A project area is located on Canal 38 (i.e., the channelized portion of the Kissimmee River, known as C-38) and begins approximately 2 miles south of the US 98 bridge and extends downstream to near the CSXT Railroad Bridge (CSXT RR) crossing over C-38. The U-Shaped Weir (S-69) site is located approximately 1500 feet upstream of the CSXT RR over C-38. Spillway and Lock 65C (S-65C) is approximately 5 miles upstream; although S-65C is no longer operated and is scheduled to be demolished and removed in May 2017 as part of the on-going KRR Contract 10 (Reach 2 Backfill). Spillway and Lock 65A (S-65A) is approximately 25 miles upstream. Spillway and Lock 65D (S-65D), Spillway 65DX2 (S-65DX2) and S-65DX1 culvert structure are located 1.6 miles downstream of the CSXT RR Bridge over C-38.

3. Water levels in the project area are mainly affected by rainfall, evaporation, local runoff, groundwater levels, operation of the Central and Southern Florida Project structures and canals in the Kissimmee River – Lake Istokpoga Basin. Water levels in the project areas will also be affected by the extent to which backfilling upstream has progressed (see Item 10 for details). Besides rainfall runoff between S-65A and S65D, S-65 discharges from the combined Lake Kissimmee, Hatchineha, and Cypress pool are the primary contributors of flow to C-38 upstream of S-65D. Lake Kissimmee, Lake Hatchneha, and Cypress Lake are operated between elevations 48.5 and 52.5 feet, NGVD, in accordance with the seasonally varying schedule shown in Figure 1. Normally, the spillway gates of S-65 are operated to permit water levels in Lakes Kissimmee, Hatchineha, and Cypress to fluctuate seasonally as shown on the regulation schedule.

Releases of up to 11,000 cubic feet per second (cfs) are made through S-65; however, S-65 is operated so that the discharge through S-65A does not exceed 11,000 cfs. When the lake stage is in Zone B, releases may be made to maintain downstream flows for water supply, navigation, and environmental purposes. The South Florida Water Management District (SFWMD) has the option

SECTION 00 33 50 Page 2 of using the Interim Operational Schedule as shown in Figure 2 as a guide for making releases from Zone B.

4. S-65A is a reinforced concrete, gated spillway with discharge controlled by three vertical lift gates and a reinforced concrete lock structure that has two pairs of sector gates. The purpose of the lock structure is to permit the use of the existing federal navigation project by small vessels and to pass maintenance dredging equipment. The spillway gates are operated manually by SFWMD to convey flow from Pool A to Pool D.

S-65A is operated within a headwater elevation range from 45.3 to 48.3 feet, NGVD, insofar as possible; however, this range may be exceeded due to hydro meteorological conditions. To the extent possible, S-65A may pass all discharges up to 11,000 cfs without exceeding desirable stages or velocities, and will restrict discharges during larger-then-design floods to 11,000 cubic feet per second (cfs).

5. S-65D is a reinforced-concrete, gated spillway with discharge controlled by four cable-operated vertical lift gates and a reinforced concrete lock structure that has two pairs of sector gates. Operation of the spillway gates is manually controlled. S-65D is operated within the headwater range from

25.8 to 28.8 feet, NGVD. It was designed to pass the design flood (30 percent of the Standard Project Flood) without exceeding the upstream flood design stage, and restricts downstream flood stages and channel velocities to the non-damaging levels of the design flood, even if the inflow exceeds that flood. However, it also passes sufficient discharge during low-flow periods to maintain downstream stages and irrigation demands. Recently constructed S-65DX2 is approximately 500 feet west of S-65D and has the same optimum headwater level as S-65D. S-65DX2 is capable of discharging up to 8,600 cfs. The operating agency has the flexibility to choose either structure (S-65D or S-65DX2) or both (S-65D and S-65DX2) to make discharges. S-65DX1 is approximately 1,500 feet west of S-65D and conveys water from Pool D to the Old Kissimmee River. S-65DX1 is capable of discharging up to 1,000 cfs.

6. Immediately upstream of S-65D is C-38 Pool D, which is located between S-65A and S-65D. Water stages in Pool D are affected by discharges through S-65A and S-65D and from local and tributary inflows to Pool D from the adjacent floodplain and uplands. Historically Pool D was the portion of C-38 that was located from S-65D to Spillway 65C (S_65C). S-65C has recently been taken out of operation. Currently Pool D extends from S-65D upstream to S-65A.

7. The contractor should be aware that the water levels and discharges might change suddenly due to Central and Southern Florida (C&SF) Project operations, and should also be aware that there could be extended periods of high discharges during the contract period, depending on the hydro meteorological conditions.

8. Historical average daily flow data for S-65A and S-65D for the period from August 7, 1970 through February 12, 2017 is presented in graphical format in Figures 3 and 4, respectively.

On January 8, 2003, 2004 an average daily maximum flow of 10,848 cfs was recorded at S-65A. On September 28, 2004 an average daily maximum flow of 20,123 cfs was recorded at S-65D. The 10th, 25th, 50th, 75th, and 90th percentile average daily exceedance curves for S-65A and S-65D flows for each day of the calendar year were compiled from the same period of record, and are presented on Figures 5 and 6, respectively. For example, for a given day in the calendar year, the “10% exceedance” curve shows the flow at which 10 percent of the flow values on that day were greater for the indicated period of record. Likewise, for a given day in the calendar year, the “75% exceedance” curve shows the average daily flow at which 75 percent of the flow values on that day were greater for the indicated period of record. While these graphs can also be used as a rough indicator of the probable seasonal variations in flows, flows outside of those shown can occur.

9. Flow exceedance curves by month for the combined total flow discharging from the downstream S-65D, S-65DX2 and S-65DX2 structures are presented as Figures 8-19. Thus, a total of twelve curves (one for each month) are provided. Developed from actual daily average flows recorded during the period 1970-2017. (Please note that S-65DX2 was not in placed into operation until 2012.) These curves provide the percentage of time that a given flow value has been exceeded when considering all of days of a particular month during those observed 47 years of record. For example, looking at the June flow-curve, a daily flow value of 3000 cfs has been exceeded 8.8 percent of the time in June during the period 1970-2017. Likewise, referring to the September flow-curve, a daily flow value of 3,000 cfs has been exceeded 30 percent of the time in September for the period 1970-2017. However, the number of days would certainly be expected to vary from the average based on the extent and effect of hydro-meteorological conditions (rainfall, evapo-transpiration, groundwater stages, tributary inflows, etc.) and water control operations on the construction site.

10. Estimates of water levels at the construction site when encountering different magnitudes of water flow have been made based on the results of a computer hydraulic model. The estimates of water stage have been made for the construction case when the eastern and western weir legs have been completed and the earthen plug has been extended across C-38 allowing for construction of the northern sheet pile weir section. The flow

vs. stage relationships at the site for the construction case of: 1) “construction bypass condition, 2) “construction with no bypass condition” are provided as Tables 1 and 2.

11. In general, historic water levels and discharges are not necessarily indicative of future levels and discharges.
