The twice-daily event causing water levels to rise and affecting freshwater sources around Jamestown is the tidal cycle. During high tide, saltwater from the nearby ocean is pushed inland, raising water levels and mixing with freshwater sources like wells and streams, making them brackish.
The twice-daily event that causes water levels around Jamestown to rise and makes wells and fresh water streams become brackish is the tide. The tidal cycle brings in seawater, increasing the salinity of the water in wells and freshwater streams located in the vicinity of Jamestown.

Crayfish live in brackish to pure freshwater. There are species that live in streams, creeks and rivers as well as some that live in lakes and ponds. The ones that you may see in the store are usually the species that live in brackish waters because they tend to grow bigger than the other species.
Freshwater ecosystems contain the least amount of saltwater compared to other aquatic ecosystems, such as marine and brackish water ecosystems. Examples of freshwater ecosystems include rivers, lakes, ponds, and streams.
Salt water and freshwater meet at an estuary, which is a partially enclosed coastal body of brackish water where rivers and streams flow into the ocean. This mixing of salt water and freshwater creates a unique and diverse ecosystem that supports a variety of plant and animal species.
I think something to do with saltwater.
Some species of crayfish, such as the spiny lobster, are saltwater animals, while other species, such as the kabby or koura, are freshwater animals. It all depends on which species of crayfish you are referring to.
Gulfs can contain either freshwater or saltwater, but most are primarily saltwater bodies connected to oceans. For example, the Gulf of Mexico is a saltwater body, while some smaller coastal areas or estuaries may have a mix of saltwater and freshwater. Freshwater influx from rivers and streams can create brackish conditions in certain parts of a gulf, but the overall classification usually leans towards saltwater.
Frogs are primarily freshwater creatures. While some frog species can tolerate brackish water (a mix of freshwater and saltwater), most frogs live and breed in freshwater habitats such as ponds, lakes, streams, and marshes. They typically do not thrive in saltwater environments.
