Freshet is the large increase of water discharge volume in a river during spring months due to snow melt on nearby mountains. This is an annual occurance that takes place between the end of April and early July. The duration depends on the amount of snow that accumulates over the winter months.
Beside a much higher water level, water clarity during freshet is also poor. The water is usually silty due to all the sediments that are carried down by the snow melt. Fishing is usually not possible during freshet.
