Tune In The Water CycleAdapted from worksheet
found at www.educationoasis.com
  • The Water Cycle
  • The suns heat causes water from oceans, lakes,
    rivers, trees, and plants to turn into water
    vapor or steam and go into the air. This is
    called __________.
  • The water vapor in the air cools and changes back
    into liquid and forms clouds. This is called
    __________.
  • When the clouds cannot hold anymore water, it
    falls back to earth in the form of rain, snow,
    hail, or sleet. This is called __________.
  • The water that falls back to earth may seep into
    the ground. This is called __________.
  • Or, the water may run over the soil and back into
    bodies of water such as lakes, rivers, and
    oceans. This is called __________. Then the cycle
    begins again.

What is a Watershed?
  • A watershed is everything in a drainage basin
  • It includes everything from the ridge-tops to the
    mouth of the largest river (Oregon State
    University Extension, 2002 1)
  • If a drop of water falls on the top of a ridge,
    it flows down one side or the other, into one
    watershed or the other (Oregon State University
    Extension, 2002 1)
  • All land is part of one watershed or another
  • All humans live in one watershed or another

Basic Elements of a Watershed
  • Water Source rain, snow and melting snowpack
  • Water Flow
  • measured at different points in the tributaries
    and the Klamath River (tributaries are smaller
    rivers that flow into the largest mainstem
    river)
  • affected by ground water storage/flow patterns
    and by storage in lakes and reservoirs,
  • affected by human use as well
  • Water Quality determined by natural and human
    factors, as well as amount of flow

8
How Does a Watershed Work?
  • A healthy watershed needs to
  • Capture water
  • Store water, and
  • Release water in timely manner

9
1. Capture Water
  • Uplands of the watershed
  • need to absorb water into the soil
  • aided by vegetative cover that helps soil hold
    water
  • Otherwise, water will quickly run off, carrying
    sediment (soil washed into river)

10
2. Store Water 
  • Some water stored in soil slowly flows through
    the soil to streams (subsurface flow)
  • Other water moves slowly through rocks for
    storage in underground aquifers (underground
    lakes)
  • Water is stored as surface water in wetlands and
    lakes
  • Humans can restore wetlands and create artificial
    lakes to store water

u/graphics/aquifersandwells.gif
12
3. Release Water 
  • Water stored underground seeps out during dry
    periods to supply streams
  • Humans tap underground aquifers through wells

13
About the Klamath Watershed
  • The Klamath Watershed
  • 12,000 square miles of Northern California and
    South-Central Oregon
  • Centered on the Klamath River, about 350 miles
    long from its headwaters east of Crater Lake, OR,
    to its mouth at Requa, CA, at the Pacific Ocean
  • Collection of smaller watersheds/basins
  • Each watershed drains into different smaller
    river that flows into the Klamath River

What is your Schools Watershed Address?
  • Is your school in the Upper or Mid/Lower Klamath
    River Watershed or is it on the Pacific Coast?
  • What river or lake are you nearest?

Why is the Klamath Watershed Remarkable?
  • Klamath Watershed contains
  • Part of Crater Lake National Park, deepest lake
    in U.S.
  • Upper Klamath Lake, the largest lake in Oregon
  • Seven National Forests
  • Six National Wildlife Refuges
  • A National Monument
  • A National Recreation Area
  • If climate change causes extensive extinction,
    the Klamath Basin will be an important place to
    preserve species for biodiversity

23
Klamath WatershedBefore Human Impacts
  • Streams flowed freely with natural fluctuations
    in the river level from winter to late summer
  • Tributaries had substantial riparian cover
    producing cold, clear water. Riparian refers to
    the zone of plants and animals that borders a
    stream, lake, or wetland
  • Summer flows were naturally low and water
    temperatures were cooler than present due to
    riparian shading in tributaries
  • (Waldvogel, 2005)

25
Klamath Watershed Before Human Impacts (continued)
  • Due to snow melt-off and rain, spring flows were
    cool and high and unimpeded by dams
  • Winter flows were occasionally very high,
    flushing out the system and providing new gravel
    spawning beds
  • Fish passage to the Upper Basin was unimpeded and
    spring Chinook runs to the Williamson and Sprague
    Rivers existed
  • (Waldvogel, 2005)

Klamath Watershed Before Human Impacts (continued)
  • Fall Chinook and steelhead runs existed as far as
    Klamath Falls and the Link River
  • Old Growth Douglas Fir and Redwoods overhung the
    tributary streams in the Lower Klamath Watershed
  • The estuary (interface between fresh and salt
    water) was deep and free flowing to the ocean
    during summer months 
  • (Waldvogel, 2005)

Blue-Green Algae in Upper Klamath Lake
  • Regarding algae in Upper Klamath Lake, sediment
    core samples demonstrate that until the 1900s,
    there was no Aphanizomenon (AFA) present,
    although there was a heavy concentration of a
    variety of other algae. (AFA is now by far the
    dominant form of algae in Upper Klamath Lake. AFA
    crashes deplete oxygen for fish.)
