Reconstructing hydrologic, physical, geomorphic, or chemical processes and patterns in a stream channel or watershed.

The raising of the elevation of the streambed through deposition of sediment eroded at another location.

Sediment deposited or transported by streams.

Species that reproduce in freshwater and spend part of adult life in the ocean.

Attached. Water rights are appurtenant to a piece of land.

Rock formation or subsurface layer in which water collects.

The portion of streamflow contributed by groundwater.

Bottom-dwelling.

Controlling erosion, sediment delivery, and floods through the use of living structures. Combination of biological, ecological, and structural concepts to achieve these ends.

A small-scale barrier made of boulders that raises water level or diverts flow.

Artificially straightening the meanders of a stream channel or river.

Cubic feet per second. A measure of streamflow volume.

A legal restriction on future development.

The flow of a stream, measured as a volume.

Removal of water from its natural channel for use in a different location.

A community of organisms and the environment with which they interact.

Management to maintain structure and function of an entire ecosystem.

In a particular year, the number of anadromous fish that reach a spawning area.

A species introduced into an environment from elsewhere.

Gone; no living representatives on the planet.

No longer present in a certain area, although populations of the species exist elsewhere.

Fields left bare and unplanted during certain seasons.

Flow regime

The pattern of stream discharge over time.

Pertaining to rivers or streams.

Wire structure filled with rocks and placed in a stream to stabilize stream banks, control erosion, and divert stream flow.

The study of landscapes and the processes that change them.

A temporary structure built to divert water.

A graph that depicts streamflows over time.

The study of the circulation of water on earth surface, subsurface, and atmosphere.

The process of water moving into the soil.

Maximum rate at which a given soil can absorb water.

Water flowing through a natural stream channel.

A stream with water part of the year.

Aquatic insects that are large enough to see without the aid of magnification.

A species that evolved in the particular environment or area that it currently resides in.

Pollution that comes from diffuse sources rather than a distinct point. Examples may be pesticides from fields, sediment from roads, or nutrients from animal excrement, carried into streams in runoff.

Stopping human activities that are causing degradation to a watershed or preventing recovery.

The highest streamflow during a period of time, typically a year.

A location at which photographs are taken to document change over time.

A deep pool created in a stream by vertically falling water.

A depression in streambed gravel dug by a female salmonid (or other fish) to lay her eggs in.

Refuges. Locations where fish and wildlife species have survived despite widespread historical disturbances.

The area alongside a stream.

Large rocks or boulders placed on a streambank to deflect energy and stabilize the bank.

The roots of an uprooted or washed out large tree.

Fish in the Salmonidae family, which includes salmon, trout, chars, whitefish, ciscoes, and grayling.

The degree of curvature of a stream.

A group of fish that is isolated geographically and is genetically self-sustaining. Typically, a local population of fish that originates and returns to a specific watershed.

A stretch of a stream between two points. The US Environmental Protection Agency has classified streams in the US into river reaches and assigned each reach a unique number.

A subdivision of a large stream basin such as the Columbia. A subbasin may contain several watersheds.

The material that composes the bed or bottom of a stream or lake.

Water that flows underground in the unsaturated layer of soil between the top of the water table and the land surface.

The process by which one plant species colonizes an area, making it hospitable to another species, which then begins to dominate, and so on until the climax species is reached.

Water that exceeds the soil's infiltration capacity and, therefore, runs overland.

Use of natural resources at a rate that can be continued indefinitely while maintaining the abundance of the resource.

Raised mounds of earth with flat tops and sloping sides, constructed across the slope of a cultivated hillside.

An area of deposited sediments from a previous floodplain that has been abandoned as river flow decreased, or as channel incised.

Areas that offer protection from heat.

A stream or river that flows into a larger stream or river.

Legal right to use water at a defined point of diversion, time, and place of use.

An area drained by a single river or river system, defined by a ridgeline.

Restoring the vegetation, soil, and stream functions that support a diversity of terrestrial and aquatic life.

A structure across a stream that raises water level or diverts flow. Can also be in the form of a notch or a depression in a dam.
