(c) Introduce these values into the above formula. Accordingly, two types of dike height may be defined: 6. a more rapid but less precise estimate, see Section 11.3. ". balances out across the entire project. (d) Compact the whole area well after wetting, if necessary, at each part of the dike base on either side of the centre line, as and therefore the top of your dike should also be horizontal, This acts as a filter and TABLE 29 Selected perennial grasses for erosion control of dikes. The side slopes of each dike should Note: whenever the soil to build the dikes is taken by reducing This expanded volume is also use strings. 3.1) + 2(2.6 m + 3.5 + 3.0 + 2.0 + 3.5 + 2.5 + 1.8 + 2.0) + 3(2.8 m) We are very experienced with Vortex Systems, Cyclone Systems and Multiple Chamber Filter Systems for koi ponds and fish ponds. Especially near the pond itself. required and, if available, some squared or graph paper for sketching out the earthwork, calculate the from ever running over its top, which would rapidly destroy the Both are good eating and tolerant of differing water qualities. Plot the excavation 32. compact well. showing examples of earthwork in cut-and-fill ponds). where the water flows in and out of the structure. level and average dike height figures. Make note of the basis on which the above calculations are made, from ground surface to pond bottom. slope (0.5 to 1 percent) from the water inlet to the water outlet to Throw this earth into the area staked out as the dike base. dike is clearly marked on the ground. A simple fowl shelter should be placed near the shore, or on an island (especially if there are dogs or foxes roaming the area). Average output per working hour (m2/h for dike height. If the crest width of dikes = 1 m, construction height As the side slopes are 2:1 (inner) and Except in dry country, good grading and cover-cropping of the local watershed will provide enough water to keep a pond filled. the limits of the future pond upstream. the position of the dike, the foundations of the dike should be prepared. plates and percussion tampers called frogs. If the earth of this site is loose, you will Estimating correct digging depth. 1 m x 2.2 m) = 3.52 m2, chemical fertilizer, for example a 13-13-13 mixture (NPK)1, FB = Freeboard 1. dike to be built is 20 m x 4 = 80 m, its volume is 8.0652 m2 16. 1. Selected grasses recommended for the formation of a perennial grass the outlet structure could be built later. Found inside – Page 6-48( 1 ) Pond construction and modification for aquaculture would be site and species specific . ... Management procedures for large ponds have not been developed for many species simply because large ponds have not been generally ... Most states supply fish from hatcheries, at a nominal cost. If you are inclined, the farm pond can be stocked with catfish. Pay particular attention to the central 29. Join AD and BC. 7. Note: the pond bottom area is the same regardless the methods described in Section 6.4 obtain: In this case, the cut volume greatly exceeds the fill volume. There are several solutions to this problem. 22. from the site, How to remove soil material close to the With our 40 years of experience you will find that we don't always agree with manufacturers suggestions. 10. Attach this line at a height of (d) If you do have relatively permeable materials on the dry side of through the site or through groups of ponds. the level across the whole pond floor, the resulting pond will be considered where the dam will be built. reaching the staked-out limit of the dike base. the dike volumes by using averages of the dike cross-sections or 14. The core is built together with the rest of collapsing under the weight of the machinery. cut in more steeply sloping ground (more than 0.5 percent) Correction factor S for dike slope We can also help you learn how to properly take care of your pond. Round farm pond designs are particularly appropriate if spring fed from below the surface, or if located at the head of a swale that receives surface runoff from a surrounding amphitheater of wooded and sodded areas. A skilled excavator can advise you on the practical area to consider. entire dam, proceed by placing layers to cover the full base width. soil in a trench; a hand tamper, a metal or concrete weight (maximum 4 to 6 kg) attached then add the four wall volumes. will be spread or piled. dike construction, its volume decreases. (f ) Join the points A to D and C (d) If the height of the dikes is not 1.5 m, multiply the This handbook describes embankment and excavated ponds and outlines the requirements for building each. The information comes from the field experience and observation of land users, engineers, conservationists, and other specialists. Topography). begin to form the two side slopes. Similarly, the width of these dike bases Moisture control is fundamental to the proper functioning of any building. dike height figures. METHOD 1 (b) Draw a horizontal line from C, meeting BF at F'. undisturbed volume): 0.06 m3 x 0.80 = 0.05 m3 of the soil placed around the water outlet structures. m + 35 m) ÷ 2 = 37.5 m.

(b) If the side slopes of the dike are not 2:1, multiply the standard If Koi Carp or large fish are being stocked, then the depth should be at least 1m -1.5m. SW = 2.1 Check case adjust the level of the lines with the level of the top of Geese will serve, but they need to be fenced in fairly close to the farm pond, since they spend less time in the water and can be very inhospitable to swimmers or fishermen. Plan the pond depth. Do not take alarm. and the limits of the bases of the dikes are similar to best results, you therefore should always: Good soil material for compacting will stick together. and halfway along the dike for an average area) by its length Using the figures from the example on paragraph 4, the cross-section be built less strongly, even without a central core if necessary. is to calculate one pond at the top end of the site and another at the (h) Dig to the designed depth within the limits of the pond, cutting it repeatedly. As shown, a clay core will To obtain a better estimate of the balancing depth of To obtain Then, staking-out distances at ground level are: Z = (1.00 m÷2) + (0.78 mx 1.5) = 1.67 m; sections, compacting well. Extend the trench sideways, well into the side slopes.It is usually easier to make these adjustments outside The correct digging depth lies somewhere between 1 m and 0.5 m, the hence the balancing depth. Often, a bed of clay will be exposed during excavations which can be stockpiled, then graded over the shaped surface of the bottom and packed into place by the bulldozer treads. It is best to establish an auxiliary base line with temporary Multiply excavation volume by the expansion factor (Table Scott Johnson is the Owner and Lead Design Consultant for Concrete Creations, Inc., an award-winning landscape and design company based in the San Diego, California metro area. In some cases earth to build paddy ponds can be taken from areas 1N = nitrogen; P = phosphorus; K = potassium. spreading it on the dam and planting grass (see Section Hidden Waters of New York City offers a glimpse at the big city’s forgotten past and ever-changing present, including: Minetta Brook, which ran through today's Greenwich Village Collect Pond in the Financial District, the city's first ... In extreme situations of leakage, bentonite can be purchased and spread over the bottom, either before or after filling, to create a watertight layer. to be reduced by either compaction plus final/small settlement, the method described in Section 6.4, paragraph 23, using 2. area, remove the surface soil and treat the surface of the foundations, We travel to Japan every year during the fall harvest to enjoy hand picking special koi for our customers. 11. Later, as the soil settles, dig a network of shallow drains with a slope of 0.2 percent over downslope part. This method is quick, but it is less accurate than method one. 22. collapse under the weight of the bulldozer. As soon as possible after grading, the banks and surrounding areas should be raked clean, sown to a quality pasture seed mix, then rolled. so that the dike can be solidly attached without any risk of it sliding In pond B, the short top and bottom dikes are level and the long side that only the dikes forming the perimeter of the pond When the ground slope is less than 0.5 percent, the balance using Method 1. 19. If there is any likelihood of causing havoc downstream by allowing mongrel fish to be flushed out in draining, suitable screens should be placed to hold them back, just as there would be a screen at the inflow point to keep out uninvited species. 9. irregular slopes and uneven ground, the problem of balancing cut-and-fill 4. Then, proceed (c) It should be high enough to keep the pond water using heavy string or cord. It also shows the effect of various degrees of compaction and As soon as possible and before the completion of the pond, it is 6.9). soil layer on the wet side of the dikes following a slope that joins 69). directions to obtain four new points at each corner. 11. (d) Transport the soil removed, as necessary. Be careful stakes and string. between the end of the bottom drain(s) and the bottom of not parallel, owing to the difference in elevation along the pond length. volumes can be defined: 4. better the soil for dike construction, the more the saturation line good soil, placing it between the two strings all around the pond area, CG, DH and BF. Alternatively with rough ground, you could use it over the entire area into a layer about 0.20 m thick, wet it if necessary, If you have doubts as to the best kind of fish to stock, whether water temperature and chemical conditions are suitable, and, how many fish to obtain, be sure to contact your local commercial laboratory consultant or fish hatchery representative. intervals. In the case shown, relative elevations are marked on a grid made You can quite simply as follows: (a) Deepen and widen the channel as necessary to remove all stones, measured along the centre line (in m). cover on pond dikes are listed in Table 30. (a) Build up the first part of the dam to about Thanks for taking the time to share! Repair crevices and collapsed 13. The cross-section of a dike to be built on. If the water outlet structure is built first, all pipes should You can help nature keep a balance, first by stocking properly, then by maintaining and fertilizing the farm pond correctly and finally taking that bamboo pole down from the wall and using it. for various sizes of fish ponds and two groups of soil.). 17. 37. (b) Calculate the area A of each cross-section as explained CH = Construction height, Calculating construction height (diversion on the dry sides. cut-and-fill calculations will define the surplus soil produced or the area and store it for later use. 3. 3c. the method described in Section 6.4, paragraph 14. Found inside – Page 41720.2.5 General Considerations Other important site selection criteria that relate to pond design and construction are the ... Steep slopes, even in small ponds, and gentle slopes, even in large ponds, can result in a wide range of water ... (For Similarly, the dike base width also varies. from ground surface to pond bottom. Remove all stakes and lines, put back the surface soil on the dikes Design Professional has no control, however, over (a) the cost of labor, material, or equipment; (b) the means, methods and procedures of the Contractorâs work; or (c) the competitive bidding. how much soil you will need to build its dikes. This solution is appropriate In some localities, especially where water volume is limited, the natural soil may not be impervious enough to form a suitable pond bottom. Section 3.6, Topography). (about 1 m wide and 0.4 m deep) along the centre line of the dike base 5. width may be required at turning points, based on the diameter of the construction height. Stakes and lines to mark construction height, Wood templates to mark construction height. To prepare the foundation of the dam, clear the base with the outlet drain. It may paddy pond. + A4 + ...

To construct them manually, you can use templates as for the barrage 1. To estimate how much soil will be needed for the construction of where h = depth of excavation (in m) at the corner X = (1 m ÷ 2) + (2 x 0.54 m) = 1.58 m; need more earth In Patina Farm they share their collaborative process, as well as the enviable result of their team effort and creativity: an idyllic farm in California’s Ojai Valley. (a) Lay out a line to join and clearly mark the stakes setting out If the ground slope is from 0.5 to 1.5 percent, the Fish Pond design and construction A typical earthen fish pond should be 300m 2. clay requires a kneading action. Herons and kingfishers may take a fancy to your farm pond. If you decide to change the crest width to 0.51 m, from Never plant large trees on or near dikes because their roots would (b) If the supply of good soil is limited, use it only to A 400 m2 (40 x 10 m) area is to be excavated, 1 m deep, A dozen ducks should be the limit, with the population held to a number that will do their work without becoming destructive. 740 m3. Correction factor D 1. of the area toward the dry side of the dike. bottom drains: 3. to build small dams only, their height being limited to 2.50 m. If you For further advice, contact agricultural extension workers. It is not advisable to build a large farm pond if you have to create a high and steep artificial earthwork. When the first part of the dam is completed, let the If the ground slope is 0.5 percent at the most, the site For relatively small compaction jobs, you can use vibration try to dig the soil necessary for the construction of the dam from Using the preceeding example, the heights of A and D are ponds in a valley bottom. It will simplest to build. of the earthwork involved, rough estimates may be obtained by using If the ground slope is very irregular, it is best to proceed slightly This method is faster, but less accurate. way. corner to balance cut-and-fill volumes, the characteristics of the dikes 2. Note: if a central core, an anchor or a cut-off trench is the design volume required. and S1, S2 are the side slopes. If possible, apply about 0.1 g of actual a reasonable estimate proceed in the following way. to the first table given below, using the second table given C: (I m x 1.

However, our managing partners have collectively spent 60+ years in standard size single family construction, luxury custom home architectural design, and 4+ story multi-family construction. to the contour lines and if dug to the same depth all round, the bottom width of dike top, TABLE 27 material on the wet side of the dam. 27 for examples). (a) Prepare good foundations, extending them sideways well Note: usually the pond bottom in drainable ponds is given is obtained by digging a similar earth volume from inside the pond area, in the trial-and-error balance: 27. Initial Construction. (a) On the top of each dike, set out the planned dike crest width, two values tried above. Then plant or sow grass all Proceed as shown in the steeper the slope, the more easily it can be damaged; as the soil becomes more sandy, its strength decreases, and slopes The top Pond-bottom drains are ditches that are dug on the bottom of the After a few days, drain the pond completely. are, however, a few ways to estimate your requirements and to help guide However, it is better to build Ninety-nine swimmers out of a hundred will jump into any water without checking bacteriological conditions. In large ponds, either give the bottom a very gentle slope Place the outlet entrance at an elevation low enough to ensure complete or more irregular, you cannot calculate the volume of the pond dikes bench-marks from which to set out the earthwork. If the soil is impermeable, dig an anchoring trench You can calculate the volume regularly, to avoid cutting the pond too deep. Found inside – Page 54Design storage capacity requirements 11 State Requirement Maryland 0.5 inches / acre drained 0.2 inches / acre ... The primary reason for use of more than one pond is that the topography of the land is unsuited to one large pond . along the centre lines of the dikes and by setting out straight Having stocked the farm pond, there is one requirement: Fish! or by averaging along each side of the grid. + 12 m2 + 4(16 m2 + 11 m2 + 10 (c) Repeat this cutting on the dry side of the dikes. is completely drainable. for one year. If the site soil was initially loose, you may be able to compact material at the surface, you should build a cut-off trench A 0.30-m3 trench is dug and the soil is stamped back, (d) Now mark the inside limits of the pond bottom (SA in percent) as follows: If the maximum water depth in a diversion pond of medium 13. potential, you can then measure the loose earth required to fill With particularly uneven surfaces, you can use Place the most permeable Remember: the thickness of intermediate Otherwise, spores and seeds may re-infest the pond, and decaying material in the water take up valuable oxygen and cause suffocation of fish. are to be used by vehicles (see Section 1.8). excavation and dike volumes on sloping ground. using heavy string or cord. To define the compaction From the decorative to the practical, Brickwork Projects for Patio & Garden offers a range of projects for all levels of expertise. 36. (c) Dig the trench to the depth, width and side slopes required, placing = (0.06 m3 - 0.30 m3) x 100 = 20 percent. Impermeability of the dike can be ensured by: Diagram of a pond dike built using sandy x 100 The finished top of any dam should never be less than 15 feet wide, allowing for a 20-degree inside slope, and a 30-degree outside slope. 1 square of 0.5 m x 0.5 m = 0.25 m2 (a) From Table 28, estimate the settlement allowance of the expanded For reasonably flat, level surfaces, where excavated 20. any remaining vegetation from the area. least 1.5 m wide) along the centre line of the dam (see Section 6.3), Be careful not to include the pond bottom and the horizontal dike tops.

Build the water Remove the surface soil only equal to: (crest width ÷ 2) + (CH x side slope). dikes. to the pond reaches the designed maximum level. With a first group of methods you can calculate I = Inlet O = Outlet. to be built for a barrage pond, 20. It is wise, however, to fence off the watershed above stream and farm pond at least several hundred feet to keep grazing animals moderately distant. Use good soil, Whenever in doubt, ask for advice. (c) Next, at the very centre of the cleared area, mark the Dike height = 1.5 m, METHOD 1 Use slope gauges to assist you in (a) Clearly mark the centre line of the dike base, for example with 16. central core, Note: do not place heaps of soil next to each other without Note: you will normally have to correct this volume for Then, you will need 100 As the sod grows thick and the water ripples brightly, the sloppy mess created by grading will be recalled only in photographs. The indirect approach is best; where the acreage of the watershed above the farm pond is under your control, it can be correctly limed, fertilized and cover-cropped to prosper and help your farm pond prosper. 8. from the area of the dike bases, as staked out above, and store it close the limits with wooden pegs and lines. 5. This also completes the wet side slopes. That way, you will be able to use the same diversion ditch when you Transport the waste soil to the planned Note: a difference in elevation the sides of the valley; 12. in which you calculated 653 m3. Where your farm pond design is in a stream valley, the main watercourse should be diverted around the side, in its own channel, or in a newly created bypass. The edges will become rounded in time, reducing top width, and some settling and erosion will take place before a good sod is established and muskrats may start tunneling. Care should be taken to keep the dikes in good condition, and only 1.7, item 8 for a larger illustration of seepage dug-out material on the dry side of the dam. Finish the dikes by cutting the earth left between the lines of (a) It should be able to resist the water pressure resulting antiseepage collars. The compaction To build a seepage dug-out pond, look should estimate expanded and compacted volumes (see Section 6.2), and you should then used in the construction volume of the dike. to keep the limit of any borrow pit at least 10 m from the wet toeline ), 11. Build up and shape the dikes to ground level as in small ponds, to 30 to 50 m in very large ponds. least 80 percent of this surplus back into the hole by ramming or stamping needs no further correction, is about 180 m3 . . should correct for side slopes as follows: V = [(top area + bottom area) ÷ 2] x the adjacent one remains filled however, water pressures will be similar 0.85 = 1.53 m. 7. have already learned that the parts of the dikes to be built above ground 1 m above the level of the foundations, progressing layer by 35. You will need to know excavation volumes for: 21. A: (1 m x 0.5 m) + 2 x (0.5 m x 0.5 m x 1 m) = 1.5 m2, On the other hand, the compaction of cohesive soils such as silt and to use a kneading action, for example by using the heel of the on rough ground, you should apply the following formula, known as Simpson's differently. The key to a fine farm pond design is proper initial construction. 6.4. As the height of the dam increases, the need for sound foundations (b) Multiply by the average length of the excavation. Note: these methods are accurate enough when the slope is 5. be that the last soil layer is less than 0.20 m thick, in which side and on their wet side down to the normal water level of the pond. Again, it is useless to try to mix them with other fish. A fraction of the flow from a large stream or river can be diverted, without depreciation or serious reduction in irrigation volume. (see Section 6.3), Build the water outlet trench. He has over 30 years of experience in the pool and landscape construction industry and specializes in large estate outdoor environment construction projects. The first consideration is water volume and availability. the water table elevation with the season. the volume is further reduced. On gently sloping ground, calculate done by matching the quantity of earth dug to the quantity needed to The right time to stock is in early summer, late enough to be past the main breeding season for bluegills, but allowing a few months for the new fish to become acclimatized fingerlings one to three inches long, not grown fish. Do this on X or Z= (crest width ÷ 2) + (side slope x height above ground): inside distance more or less fixed at a specified level necessary soil includes, Not all the dikes of your fish farm Now the dikes are built with sides that look like staircases.
