Michigan.gov - Water Management - Glossary:
Low Flow - minimum flow through a watercourse which will recur with a stated frequency. The minimum flow for a given frequency may be based on measured data, calculated using statistical analysis of low flow data, or calculated using hydrologic analysis techniques. Projected low flows are used to evaluate the impact of discharges on water quality. They are, for example, used in the calculation of industrial discharge permit requirements.

“Use of a particle-tracking Model for predicting entrainment at power plants on the Hudson River
…
Although the average probabilities of entrainment across all river regions estimated with the particle-tracking model and the ETM were relatively similar for some power plants at high flow, low flow, or both, the probabilities for each river region differed considerably between the models.”

Flood flow
Flow of water from a reservoir down a spillway. This happens when the reservoir overflows because of heavy rain in its catchment.

Mississippi Tide, Sun, Moon Information - Glossary :
- low water -- (abbreviated LW; or low tide). The lowest limit of the surface water level reached by the lowering tide. Low water is caused by the astronomic tide-producing forces and/or the effects of meteorological, hydrologic and/or oceanographic conditions.
- high water -- (abbreviated HW; also called high tide). The highest limit of the surface water level reached by the rising tide. High water is caused by the astronomic tide-producing forces and/or the effects of meteorological, hydrologic and/or oceanographic conditions.
