As used in this chapter, "low head dam" means a manmade in-channel structure in a watercourse that is capable of generating hazardous recirculating currents that pose a risk to public health and safety and causes the watercourse to have a vertical drop of twenty-five (25) feet or less. The term does not include:

1. (1) a dam with a downstream structure in place to dissipate the hydraulic energy of the water past the crest of the dam; or
2. (2) ramped impoundments which drop at slopes of five percent (5%) or flatter.
