I have a trapazoidal lagoon and would like to calculate the cf of water it will hold. Does anyone know the formula?

Measure the acute angle of the trapezoid. The volume is the product of two adjacent sides times the depth times the sine of the angle.

Not sure what you mean by a "trapezoidal lagoon", but I assume the surface is a trapezoid and the bottom is a smaller trapezoid. If you extended the "slant edges" downward, they'd come to a point, forming a pyramid. Get the volume of that pyramid, using the lagoon surface as a base; then the same using the bottom as a base. The difference in the two volumes is what you want.

Find the area of the trapezium andmultiply by the depth of water and you get the cft of water (if all the dimensions are in ft)
