1 Small Dam Repair The Stone Lake Dam Story Joe Barron, P.E. SynTerra formerly the Fletcher Group, Inc. 148 River St. Suite 220 Greenville, S.C

2 Historical background of Stone Lake A series of three lakes built by the Stone family in the 1960 s Development of subdivision in City of Greenville, SC Built roads over dams dam belongs to Home Owners Association, roads to City 2

3 Middle and upper Stone Lake Dams Lower Stone Lake Dam the project site 3

4 Experience with State Park dams Table Rock State Park Dam Old CCC dam for mountain lake 60 feet high with internal spillway gate leaking. Couldn t lower lake because of Legislative conference. Santee State Park Dam: lowcountry farm pond size dam with leaking gate. Couldn t drain because of backwater from hydro reservoir. Put on Scuba to remove old gate. 4

5 Notification of Problem Inspection by South Carolina Department of Health and Environmental Control (DHEC) noted problems in the spillway 5

6 Dam Classification High Hazard by DHEC Significant property damage with downstream flooding 6

7 Terms Spillway refers to the 48 inch concrete pipe primary spillway Drain refers to the 12 inch steel pipe drain for the lake 7

8 Spillway A brick and concrete spillway controlled the water level of the lake and then drained to the spillway pipe 8

9 Cracking was noted in the spillway apron 9

10 Condition of pipe interior Note the water coming through the pipe disappears about 3 joints up the pipe and comes out under the pipe A catch basin in the street above appeared to be bearing on the pipe 10

11 11

12 12

13 Additional concerns A street culvert that used to discharge into the spillway pipe and was later diverted to discharge below the dam 13

14 Additional problems Steep slopes, hard to walk on, much less maintain Tree growth and root system weakens dam 14

15 Down stream erosion 15

16 Lake drain pipe Concern over the 12 inch diameter pipe under the dam used to drain the lake Could not find the end Water spilling out around some tree roots 16

17 Options Just seal the joints on the main overflow drain and dig out the end of the drain and keep watching the dam Take the opportunity to remove the trees, reslope the dam, rebuild the overflow spillway, and study the hidden drain for possible repairs 17

18 The plan The City and Homeowners Association opted for the more expensive route believing that a band aid was not adequate and that more extensive problems might be uncovered during the work 18

19 Hydrology and Hydraulics Suburban watershed with two lakes upstream Recently studied by City consultant Concluded that spillway pipe was correctly sized 19

20 Characteristics of dam Height Width at top Width at bottom Length at top Length of Primary Spillway Size of Primary Spillway Size of Drain 30 feet 45 feet 125 feet 250 feet 85 feet 48 inch diameter 12 inch diameter. 20

21 21

22 22

23 The battle plan Add a new junction box at the location of the disjointed spillway pipe The spillway will turn at this point and discharge at a lower point to allow the most serious area of downstream erosion to be filled and grassed 23

24 24

25 25

26 The battle plan Cut all trees, remove stumps and reslope the back of dam Clear end of drain and inspect with video Place toe drain of stone wrapped in filter fabric to catch seepage under dam 26

27 27

28 28

29 Construction Begins 29

30 Clearing and Grubbing 30

31 Changes to recommendations on drains & filters Prior to the 1980 s seepage collars were recommended and in some cases required around the piped drains through dams Starting then a number of studies indicated that seepage collars were not working due to the difficulty of compaction around them Pipe filters of sand and stone are now recommended 31

32 32

33 Challenges and solutions 1 More seepage than anticipated, but all under the dam, not through it Revise Toe filter to utilize a sand and stone filter Add a monitoring point 33

34 Challenges & Solutions 2 Significant root systems Anticipated Encouraged that no seepage was noted around the roots 34

35 Challenges and solutions 3 Spillway pipe crumbled when removed, not reinforced, raised concern for pipe left in place. Dig and replace or slipline? Dig up and replace would mean redoing the road and replacing pipe that did not appear to have seepage problems around it. 35

36 Sliplining options Smooth core aluminum pipe to slide inside 48 problem concrete pipe is not completely round and joints are not even Use resin impregnated fabric to seal the pipe would not provide any structure or strength but would eliminate seepage City had Insituform company under contract to slipline sanitary sewer 36

37 What would you do? 37

38 Challenges and solutions 4 Drain under dam was uncovered, inspected with video, proved to be in bad shape Decided to plug with flowable fill Add siphon drain over dam, under road instead of through dam 38
