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.

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.
An embryo becomes a fetus at around 9 weeks of development.
A maggot will become a fly through metamorphosis. The maggot is usually the larval stage in the life cycle of a fly.
The time it takes for a pupa to become a butterfly can vary depending on the species. On average, this process typically takes around 7-14 days. During this time, the pupa undergoes metamorphosis before emerging as a fully formed butterfly.

Wells and freshwater streams become brackish primarily due to the intrusion of saltwater, often as a result of rising sea levels or excessive groundwater extraction. When the natural balance between freshwater and saltwater is disrupted, saline water can seep into aquifers or freshwater bodies. Additionally, coastal flooding and storm surges can also introduce saltwater into freshwater systems. This change in salinity can adversely affect aquatic ecosystems and water quality for human use.
Streams often merge with one another to become rivers.
