South llano river one of 2011 stop ten

South Llano River: One of 2011’sTop Ten

  • National Fish Habitat Action Plan named SLR as “water to watch”

  • WHY??

    • Conserve freshwater, estuarine, and marine habitat

      For more information go to www.fishhabitat.org


Guadalupe bass initiative

Guadalupe Bass Initiative

  • Central Texas endemic (streams of the Edwards Plateau region)

  • State Fish of Texas

  • Declining numbers

    • Decreased stream flow

    • Habitat degradation

    • Hybridization with smallmouth bass


A watershed

A Watershed

  • An area that drains to a common waterway, such as a stream, lake, estuary, wetland, aquifer, or even the ocean.

What does a watershed look like

What Does a Watershed Look Like?

  • There are watersheds of all types

    • They can include farmland, rangeland, small towns or large cities

    • They can be only a few acres to millions of square miles

    • Watershed have four major features: uplands, floodplains, riparian zones, and water-bodies

      WE ALL LIVE IN ONE!!

Uplands

Uplands

  • Area of land above a water-body

    • Typically forms watershed boundaries

    • Provides habitat for wildlife, minimizes soil erosion and acts a filter

Floodplains

Floodplains

  • Flat land that surrounds a water-body that is prone to flood events

    • Traps excess water

    • Filters sediment

    • Provides habitat for wildlife

Source: Texas Watershed Stewardship Program Workshop April 2010


Riparian zone

Riparian Zone

  • “River Bank”

  • Interface between land and water-body

    • Filters sediment and surface runoff

    • Minimizes soil erosion

    • Provides habitat for wildlife

Water body

Water-Body

  • Stream, river, pond, lake, reservoir, estuary, bay, or ocean

  • Flowing (lotic) or non-flowing (lentic)

  • Influence and affected by soil, slope, vegetation and topography

Watershed hydrology

Watershed hydrology

  • Hydrology is the study of water

  • 70% of the Earth’s surface is water

  • Water continually cycles through a process known as the water cycle


The water cycle

The Water Cycle


Where does the rain go

Where Does the Rain Go?

  • Runoff

  • Absorb by plants and used for photosynthesis

  • Infiltrate soil and percolate down into groundwater aquifers

  • Evaporation

  • Trapped in ice caps, glaciers, lakes, and reservoirs

Land use land cover

Land Use/Land Cover

  • Land use is how WE use the land

    • Agriculture, industry, urban, recreation

  • Land Cover is the physical and biological features

    • Forests, grassland, rivers, buildings

  • Changes can effect watershed function


Watershed functions

Watershed Functions

  • Hydrological

    • Water capture: captured from rainfall and infiltrates into soil

    • Water storage: stored in areas between soil particles and soil profile

    • Water release: released underground, through soil, or across land

Watershed functions1

Watershed Functions

  • Ecological

    • Provides areas for nutrient transformation found in air, water, and soil

    • Provides habitat for plants and wildlife

Benefits of a watershed approach

Benefits of a Watershed Approach

  • Hydrologically and geographically defined

    • Considers many stressers (air, water, land)

  • Includes all stakeholders

    • Agencies (federal, state,& local)

    • Community-based

  • Identifies and prioritizes water resource issues (e.g. water quality, water quantity, invasive species)

What is a watershed conservation plan

What is a Watershed Conservation Plan?

  • Helps identify and prioritize issues facing the watershed

  • Framework for community participation in land and water management with regard to issues

  • Guide restoration efforts with regard to important species (e.g. Guadalupe Bass)


So why the upper llano river watershed

So, Why the Upper Llano River Watershed?

  • EPA’s Healthy Watersheds Initiative

    • Collaborative systems-approach to protecting healthy watersheds

  • Why do it?

    • Provides clean water for healthy ecosystems

    • Habitat for fish and wildlife

    • Drinking water

    • Recreational opportunities

    • Reduces vulnerability from negative impacts (e.g. land use changes, exotic & invasive species)
