Title: Great Salt Lake Basin Hydrologic Observatory


1
Compact Western Intermountain Metro-Shed
Hydrologic Observatory
A Hydrologic Observatory to advance understanding
of the hydrology of the modern west Focused on
the interactions between human influences and
hydrologic processes.
2
Three Basins of Hydrologic Significance
3
High gradients in topography, climate, land use,
GW residence times. A breadth of disciplines.

Proposed Infrastructure
  • 1.5 Million Private Foundation Grant for
    Critical Infrastructure in the Weber River Basin
    Focus area
  • Flux tower in high elevation subalpine forest
  • Precipitation
  • Surface Energy Balance and ET
  • Tunable diode laser absorption spectrometer for
    atmospheric water vapor isotope analysis and
    moisture flux component separation
  • SNOTEL upgrades to include soil moisture, solar
    radiation, humidity and wind

11
Proposed Infrastructure - Real time Water Quality
Sensors
  • pH
  • Conductance
  • DO
  • Temperature
  • Turbidity

12
Proposed Infrastructure - Laboratory Analytical
Capability
  • Trace metal species concentrations in complex
    matrices (hypersaline water and wetland
    sediments)
  • High Performance Liquid Chromatograph (HPLC)
    interfaced to Inductively Coupled Plasma Mass
    Spectrometer (ICPMS) with an Octopole Reaction
    System

13
Proposed Infrastructure - Buoy or platform on the
Great Salt Lake
  • In cooperation with NOAA National Buoy Data
    Center
  • Vertical profiles of temperature and salinity
  • Air temperature, humidity, atmospheric pressure,
    solar radiation, wind
  • Wave height and surface currents

14
Proposed Infrastructure - Spread Spectrum
Communication Network
  • Point to multipoint Ethernet communication
  • In partnership with National Weather Service,
    Federal Aviation Administration and State Natural
    Resources and Air Quality agencies
  • Enhancements and Upgrades to FAA Frances Peak
    Communication Infrastructure

15
Proposed Infrastructure - Deep multilevel
groundwater sampling well
  • Greater than 300 m deep
  • East of Great Salt Lake
  • Sample isotopes for inference of residence times
    of water emanating from mountain block

16
Component Coordinators
  • Precipitation
  • Jim Steenburgh
  • Evapotranspiration
  • Dave Bowling
  • Catchment Hydrology
  • David Tarboton
  • Snowpack Hydrology
  • Danny Marks
  • Mountain stream hydrology
  • Jack Schmidt
  • Subsurface Hydrology
  • Kip Solomon
  • Aquatic Biogeochemisty
  • Bill Johnson, Dave Naftz
  • Paleohydrology
  • Katrina Moser
  • Human Hydrology
  • Craig Forster
  • Integration
  • Luis Bastidas
  • Remote sensing
  • Christopher Neale
  • Database management
  • Rob Gillies

17
Strategy
  • Focus on strength compactness
  • Synergy
  • Logistical tractability

18
AGU feedback (paraphrased summary by Danny Marks)
  • HO needs a coherent measurement and
    infrastructure plan that will be attractive to
    hydrologists from nationally.
  • The stated science questions and themes should
    not be limited to site or regional significance.
  • 25 million wont go very far in a 100,000 km2
    basin it is a drop in the bucket, but even for a
    6500 km2 catchment it wont do much.
  • The HO must provide basic and critical data as
    well as research and technical support for as
    broad a range of hydrologic science issues as
    possible.
