Watersheds Watersheds An area of land that drains rainfall and snowmelt into a particular body of water. Pennsylvania is host to 83,184 miles of streams and rivers. The terrain determines the shape of the watershed. The area that separates watersheds is called a divide. An area of land that drains rainfall and snowmelt into a particular body of water.

Where does the water come from? The Water cycle keeps the watershed full. Groundwater-stored until it comes out in springs Surface water-water above ground The Water cycle keeps the watershed full. Groundwater-stored until it comes out in springs Surface water-water above ground

Where is the best quality water? A forested watershed has the best water! Why? 1. Water flows from the soil. 2. Soil is very porous and acts as a filter. 3. Soft forest floor cushions falling rain so soil doesn’t erode into streams. 80% of PA drinking water is from forested watersheds A forested watershed has the best water! Why? 1.

Freshwater systems Lentic systems--- Lakes and ponds 1. Still or almost still water 2. Organisms require less oxygen 3. Warmer temperatures 4. Eutrophication can occur as the nutrients build up in the lake over time. Lentic systems--- Lakes and ponds 1. Still or almost still water 2. Organisms require less oxygen 3. Warmer temperatures 4.

Lotic systems--- Streams and rivers 1. Flowing water 2. Organisms need more oxygen 3. Colder Temperatures 4. Organisms have adaptations to help them withstand the constant movement of water Lotic systems--- Streams and rivers 1. Flowing water 2. Organisms need more oxygen 3. Colder Temperatures 4.

Wetlands A land area that is covered with a shallow layer of water during some, or all, of the year. 3 types of wetlands 1. Marshes - grassy areas covered by shallow water or a stream 2. Swamps - flooded forests, with trees and shrubs sprouting from the water 3. Bogs - common in cooler northern areas, tends to be acidic, and mosses thrive A land area that is covered with a shallow layer of water during some, or all, of the year. 3 types of wetlands 1.

Importance of Wetlands 1.Provide rich habitat for many living things. 2.Filter pollutants from waters. 3.Control floods by absorbing extra runoff from heavy rains. 1.Provide rich habitat for many living things. 2.Filter pollutants from waters. 3.Control floods by absorbing extra runoff from heavy rains.
