How do lakes have rip currents?

Currents in lakes are caused by winds at the surface, temperature patterns and bathymetry, and the ‘Coriolis force’. The load on the lake is proportional to a power of the wind speed, usually assumed to be 2, although of course it varies according to wind speed, wave conditions and atmospheric stability. A current is simply… Continue reading How do lakes have rip currents?

Where does lake gets its water?

The water they carry comes from precipitation and melted snow and ice. When the water leaves a lake through a river or other outlet, it is called open. Like artificial reservoirs and lakes, natural lakes can be replenished by rivers and streams. Water enters reservoirs and man-made lakes mainly from the rivers and streams that… Continue reading Where does lake gets its water?

Is it safe to swim in lakes that are green?

You can address these concerns by figuring out how your lake will be used and managing it specifically for that use. In any case, these are the three main culprits. On the other hand, certain lakes can appear particularly green because of a high proportion of chlorophyll-containing algae. Filamentous green algae, for example, can form… Continue reading Is it safe to swim in lakes that are green?

Why is lake green after rain?

The more phosphorus present, the more frequent algae occur and the greener the water becomes. Clear lakes with little algae and other organic material are often blue in colour (left), while lakes with high levels of nutrients and algae are green (centre) and lakes surrounded by heavily forested watersheds, wetlands or marshes can be brown… Continue reading Why is lake green after rain?

Do lakes have dangerous currents?

On windy days, one can observe parallel “streaks” forming on the water surface that continue for a certain distance. Some of these are slow-moving masses of water that can be felt but offer little resistance to swimming. Shear forces that develop between these layers cause a movement called internal ripples, which can serve to directly… Continue reading Do lakes have dangerous currents?

Can whirlpools happen in lakes?

In areas downstream of weirs (which in turn lead to many drownings) or dams, whirlpools can form. In places with multiple reservoirs, they can occur in a reservoir downstream of the dam for an upstream reservoir. Within a single reservoir, spillways, especially bell spillways, can cause the formation of eddies. The circular flow had a… Continue reading Can whirlpools happen in lakes?

What causes a whirlpool in the water?

Whirlpools can also form in rivers and are very common at the base of waterfalls. Recently, scientists discovered a huge whirlpool in the Indian Ocean off the coast of Western Australia near Perth. The circular current was spinning at 5 kilometres per hour (3 miles per hour). As actress Naya Rivera and her young son… Continue reading What causes a whirlpool in the water?

Where is the best place to fish in a lake?

The shores around the lakes are fully equipped for recreation and offer many activities for non-fishing family members. There are many bait and fishing shops around the lake. The best time to fish at the lake is early morning. Although the lake is huge, it is relatively shallow, so the water warms well during the… Continue reading Where is the best place to fish in a lake?
