This map shows the Colorado River from the Hoover Dam to Lake Powell. Select whether the water of the river has potential energy (P.E.) or kinetic energy (K.E.) at each location listed below.
Hoover Dam & Glen Canyon Dam: P.E. (potential energy) due to high elevation.
Colorado River: K.E. (kinetic energy) due to flowing water.
Lake Mead & Lake Powell: Mix of P.E. (stored water) and K.E. (flowing water).
Hoover Dam: P.E. - The water is at its highest elevation here, held back by the dam, giving it significant gravitational potential energy.
Glen Canyon Dam: P.E. - Similar to Hoover Dam, the water is behind the dam at a high elevation, possessing potential energy.
Lake Mead: P.E. - While lower than the dams, Lake Mead is still a large body of water at a considerable elevation, storing potential energy.
Colorado River: K.E. - As the river flows between the dams and towards Lake Powell, it gains kinetic energy due to the pull of gravity and the gradient of the riverbed.
Lake Powell: P.E. and K.E. - Lake Powell has a mix of potential and kinetic energy. While most of the water is stored at a certain elevation (P.E.), some water might be flowing into the lake or within it (K.E.).
