1 Hydrology PLHS D. Blanck, MS
Lake Formation Hydrology PLHS D. Blanck, MS

2 1. Kettle Lakes Formed during the process of glacial retreat.

3 2. Tarn Lakes Carved through glacial erosion (plucking)

4 3. Natural Reservoirs The natural drainage of a river is blocked by debris Volcanic, Landslide, Beaver Dam, Ice Glacial Lake Agassiz was an “Ice Block” reservoir.

5 3a. Manmade reservoirs Formed after the construction of flood control or hydroelectric dams

6 4. Oxbow lake Cut-off river meanders

7 5. Rift Zone lake Form in divergent plate boundary depressions

8 6. Crater Lakes Form in impact craters and volcanic calderas
Manicouagan Lake, Quebec. Formed 200 million years ago - Impact Crater Lake, Mt. Mazama, Oregon - Volcanic

9 7. Karst Lake Water fills a sinkhole after the roof of a limestone cave collapses
