DETAILED DESCRIPTION OF THE INVENTION Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference characters refer to the same or similar elements in all FIG.s. FIG. I illustrates a perspective view of one embodiment of the present invention showing a panel 1 having plate S. As depicted in FIG. 1, the plate 5 of the panel I has an outer surface 10, a top edge 20, and a bottom edge 25. The bottom edge 25 is adapted to be disposed upon a ground surface. The plate 5 is attached to a first flange 40 at the first edge 30 of the plate 5. The plate 5 is attached to the second flange 60 at the opposing second edge 35 of the plate 5. FIG. I depicts the outer face 50 of the first flange 40 and the outer face 70 of the second flange 60. FIG. I illustrates the first flange 40 having holes 55. In one embodiment of the present invention, the holes 55 are unevenly spaced, having a higher density of holes 55 toward the bottom of the first flange 40. The second flange 60 has pegs 75. In one embodiment, the pegs 75 extend in direction normal to the outer face 70 of the second flange 60 and are adapted for penetration of the holes 55. Similar to the holes 55 and in one embodiment of the present invention, the pegs 75 are unevenly spaced with a higher density of pegs disposed at the bottom of the second flange 60. The higher density of holes 55 and corresponding pegs 75 disposed 4 toward the bottom of the first and second flanges provides for and accommodates more water to be placed in the reservoir. The additional water places more pressure toward the bottom of the flanges and a higher density of holes and pegs stabilize the bottom portion of the structure and further secures the connection between interconnected panels. In many embodiments of the present invention, the pegs 75 are integrally formed with the second flange 60. FIG. I illustrates crossbars 90 that are used to attach temporarily a panel connector piece of a front end loader or tele-handler for transportation. Thus, a front end loader or tele-handler can easily manipulate and transport a panel during reservoir frame construction. In one embodiment, the crossbars 90 may be attached to the outer surface 10 of the panel 1. Additionally, FIG. I depicts horizontal support beams 95 to further secure and strengthen the panel I and plate 5. The horizontal support beams 95 are generally parallel to the top edge 20 and the bottom edge 25, and the horizontal support beams are disposed between the first edge 30 and opposing second edge 35. In another embodiment the crossbars 90 may be attached to the horizontal support beams 95. In one embodiment of the present invention the panels have a curvature such that when numerous panels are interconnected via the pegs 75 and holes 55, a generally circular reservoir frame system is constructed. The curvature is generally convex relative to the outer surface and concave relative to the inner surface. In various embodiments of the present invention, the first flange 40 is integrally formed with the plate 5. Likewise, the second flange 60 is integrally formed with the plate 5, in many embodiments of the present invention. FIG. 2 illustrates a front view of the top of the embodiment of the present invention as depicted in FIG. 1. FIG. 2 further depicts the pegs 75 and holes 55 having a higher density of 5 both at the bottom portion of the flange. FIG. 2 shows one embodiment of the present invention wherein the pegs 75 and corresponding holes 55 have a larger diameter toward the bottom portion of the first flange 40 and the second flange 60. This further secures connection between panels because the lower, larger diameter pegs 75 have additional sheer strength and are able to accommodate greater pressures against the inner surface of the panel 1. FIG. 3 depicts the inner surface 15 of the plate 5 of the panel I having a top edge 20 and a bottom edge 25. The plate 5 is attached to the first flange 40 at the first edge 30. The plate 5 is attached to the second flange 60 at the opposing second edge 35. FIG. 3 depicts the first flange inner face 45 and the second flange inner face 65. FIG. 3 illustrates the first flange 40 having holes 55. The second flange 60 has pegs 75. FIG. 4 depicts a perspective view of the outer surface of two panels prior to connection of the two panels. The pegs 75 of the second flange 60 of one panel will penetrate the holes 55 of the first flange 40 of another panel. In this representation of the present invention the second flange outer face 70 is aligned opposite the first flange inner face 45 (not depicted). FIG. 5 depicts a perspective view of the outer surface after the connection of two panels. In this representation, the outer face 75 of the second flange 60 contacts the inner face (not depicted) of the first flange 40. The pegs 75 penetrate the holes 55. Furthermore, FIG. 5 depicts pins 85 penetrating the pegs 75 in order to further secure the interlocking panels. FIG. 6 depicts a perspective view of the inner surface of two panels prior to the interlocking connection. FIG. 6 is the inside view of the invention shown in FIG. 4, i.e., prior to connection of panels. 6 FIG. 7 depicts a perspective view of the inner surface after the connection of two panels. FIG. 7 depicts the inside view of the invention shown in FIG. 5, i.e., when connection of the panels occurs. FIG. 8A depicts the pin 85 and the peg 75 with a cut out representation of the eyelet 80 to accommodate penetration of the pin 85. FIG. 8B more depicts the pin 85 penetrating the peg 75 through the eyelet as show previously in FIG. 8A. The pin 85 goes through the peg 75 via the eyelet 80 (not depicted). In one embodiment of the present invention, the eyelet 80 is at an angle of roughly 450 relative to the bottom edge 25. FIG. 9 depicts a top perspective side view of panels fully connected and creating a circular reservoir frame of interlocking panels. The interlocking panels form a variety of shapes in various embodiments, including oval and circles. FIG. 10 shows a liner 105 covering the inner surface of the reservoir frame and the bottom of the reservoir. FIG. I1 illustrates a perspective view of one embodiment of the present invention showing panels having vertical support beams 150. Such vertical support beams further secure and support the reservoir panel 1 and plate 5 in order to hold and contain large amounts of liquid in the reservoir frame. It is believed that the apparatus of the present invention and many of its attendant advantages will be understood from the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components without departing from the scope and spirit of the invention and without sacrificing its material advantages.
