A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.

Streams and smaller rivers that feed into a main river are called tributaries. Streams and smaller rivers that feed into a main river are called tributaries. The land area that supplies water to a river system is called a watershed. The land area that supplies water to a river system is called a watershed.

Answer Expert Verified. The Florida Everglades is best described as a freshwater marsh. You can see some of endangered species water animals in this place. It is a massive amount of water and plants like mangroves filled with different types of animals including snakes, crocodiles and frogs, or even bugs are found.

Florida Bay is the bay located between the southern end of the Florida mainland (the Florida Everglades) and the Florida Keys in the United States. It is a large, shallow estuary that while connected to the Gulf of Mexico, has limited exchange of water due to various shallow mudbanks covered with seagrass.

Marshes, bogs, and lakes are examples of freshwater wetlands. You just studied 12 terms!

There are 4 main types of Freshwater Wetlands in North America; Ponds, Marshes, Swamps, and Peat bogs. A Marsh is usually found near a river, lake or tidal waters. Marshes are subject to periodic flooding, and the water level can change drastically in a short amount of time.

Types of Wetlands

• Marshes.
• Swamps.
• Bogs.
• Fens.

A swamp is an area of land permanently saturated, or filled, with water. Many swamps are even covered by water. There are two main types of swamps: freshwater swamps and saltwater swamps. They are often named for the type of trees that grow in them, such as cypress swamps or hardwood swamps.

To dig a pond with a bulldozer, you need to map the land, find the water source, and use the front blade to push out the dirt from the perimeter. Use a backhoe attachment to dig through the soil and create ledges along the way. Use liners, small rocks, and boulders to help with water retention.

An artificial bog can purify water, filtering gray-water and runoff, which improves its quality for fish, other animals and plants. It can make a pond look larger without losing as much water to evaporation as an open pond. The water from an existing pond also can be allowed to back into a bog.

Springs. Spring-fed ponds may not require any surface runoff to keep them full, meaning they will be clear, clean and cold. Using spring water to fill your pond may trigger permit requirements in some locations, but it is the ideal source of water for a farm pond.

Front-end loader buckets can be used to dig a pond. They come as small as 48” wide for a capacity of 13.9 cubic feet of material (heaped SAE rating). They may also be as wide as 108” for a capacity of 32.3 cubic feet (heaped SAE rating), or wider for larger machines.

Plants are great natural filters, making use of excess nutrients which can cause issues with water clarity. Adding pond plants is one of the best long-term ways to keep pond water healthy and clear; and the more you can add, the better!

A bog filter is an area dedicated for the dense planting of water-loving marginal or bog plants. It is a smaller, supplementary pond usually 10-20% of the size of the main water feature. The bog filter can be located inside or adjacent to the main pond.

Bog filters are extremely efficient at removing nutrients from the pond water. This mission is accomplished by pumping pond water evenly though a gravel bed via a grid of perforated pipework. The gravel provides the surface area for nitrifying bacteria to colonize.

For spring and winter water-crowfoot (Ranunculus aquatilis) is to be recommended and in summer and autumn hornwort (Ceratophyllum demersum), pondweed or waterweed are to be preferred. Other well-known oxygenating plants are mare’s-tail (Hippuris vulgaris) and water violet (Hottonia palustris).

There are two paths you can go down in addressing these issues:

1. 1: Treat weeds and algae blooms with herbicide or algaecide.
2. 2: Use natural remedies to stop nutrient pollution.
3. Prevent Excess Nutrients with Natural Bacteria and Enzyme Blends.
4. Treat the Source of Pond Problems by Adding Aeration.

For most purposes, a bog filter whose surface area is 10% of the surface area of the main pond will suffice, with up to 20% or more for heavy loads. Intense sunlight and high temperatures stimulate algae growth and so require higher performing bog filters, while lower temperatures and light levels reduce demand.

At a Glance: How to Keep Pond Water Clear

1. Understand that a little bit of algae or discoloration is normal.
2. Use beneficial bacteria to starve single-cell algae that turns water green.
3. Add a wide variety of aquatic plants to starve string algae.
4. Add a larger biofilter.
5. Don’t overfeed your fish.
6. Don’t overcrowd your fish.

Since baking soda is highly alkaline and reacts when mixed with an acid, many people assume it can be used to change the pH of a pond to discourage algae growth. However, even a large amount of baking soda dissolved in a pond will have little to no effect on either algae or pH.

Not only do pond pebbles keep your water clean, they create a natural looking bottom layer and help to provide a safe habitat for your fish. Although one thing to bear in mind is that pebbles would only be beneficial for smaller garden ponds, as larger ponds with muddy bases are likely to swallow up these pebbles.
