The only natural lakes in Oklahoma are a series of oxbow and playa lakes. The typically crescent-shaped oxbow lakes are found in abandoned channels (oxbows) of a meandering stream and occur mainly on flood plains of the major rivers, such as the Red, Arkansas, Washita, North Canadian, and Verdigris Rivers in eastern and central Oklahoma. Oklahoma has sixty-two oxbow lakes, each of which covers at least ten acres, and the largest, near the Red River in McCurtain County, is 272 acres.
Playa lakes form in shallow, saucer-like depressions scattered across the semiarid High Plains region of northwestern Oklahoma and the Panhandle. These water bodies are characterized by internal drainage and have no outflow. They hold water during and after rainy seasons, and most of the water is lost through evaporation and/or seepage into the ground. Only a few playa lakes last year-round, but the intermittent or ephemeral playa lakes number about six hundred and appear following thunderstorms.

All Lakes in Oklahoma are man made
none
Oklahoma has the most manmade lakes in the United States.
I believe around 10,000 lakes.
there are a number of state parks in Oklahoma- with the vast majority in the eastern part of the state where many of the large man made lakes are located, Grand Lake-- Lake Hudson-- Tenkiller and Fort Gibson just to mention a few.
none of the great lakes are man made all of them were made from nature
No they are not.
MAN-made resources are resources created by man. E.g.buildings,bridges,cars and furniture.
yes.
Lakes Waccamaw and Mattamuskeet
All lakes in Georgia are man made. This does not include the swamp in south Georgia which are natural, protected wet lands.
Cuba has many lakes. The largest man-made lake is Presa Zaza. The largest natural lake on Cuba is Laguna de Leche.
Absolutely. Many lakes are man-made, and there isn't a lake on the planet that doesn't qualify as a landform. In addition, some rivers, beaches, and hills are also man-made.
No. Portage Lake in Pinckney Michigan was not man made. :)
