Title: BRINGING THE TOOLS TOGETHER


1
BRINGING THE TOOLS TOGETHER
  • Glenn Patterson

2
2002 Report to Congress
3
How do we measure water availability?
  • At its core, a water availability assessment
    tells us the status and trends in storage
    volumes, flow rates, and uses of water for a
    given area.
  • Water quality must be considered.

4
Flow Rates means
  • Runoff
  • Recharge
  • Evapotranspiration
  • Interbasin transfers, and
  • Other components of the water cycle

5
And speaking of runoff monitoring
  • Each year some new streamgages are installed and
    some are discontinued.
  • Even with the increases we are likely to see a
    net reduction in the size of the network due to
    reductions in budgets of our funding partners.
  • Many of the discontinued streamgages have long
    periods of record.

Water Availability as a National Issue
  • CENR Subcommittee on Water Availability and
    Quality (SWAQ)
  • 05 Report-Science and Technology to Support
    Freshwater Availability
  • http//www.ostp.gov/NSTC/html/swaqreport_2-1-05.pd
    f
  • Upcoming reportSpring 2007
  • Working Groups

10
SWAQ Working Groups(so far)
  • Microbial Source Tracking
  • Improve Hydrologic Prediction Models and Their
    Applications
  • Collaborative Tools and Processes for US Water
    Solutions

11
Water Availability in the West
  • USGS Circular 1261 by M.T. Anderson and L.H.
    Woosley (Published in 2005)

http//pubs.usgs.gov/circ/2005/circ1261/
12
Many of the same issues discussed on todays
agenda, plus
  • Patterns of ground-water declines

13
  • Water-use patterns and distribution

14
  • Consumptive water use

15
Water quality and habitat issues
  • Urbanization
  • Irrigation return flows
  • Naturally occurring arsenic
  • Saltcedar
  • Mines
  • Endangered species, biodiversity, and habitat

16
Making the information useful to Managers
  • Weve seen a variety of tools and techniques that
    can help determine water availability. How can
    the information be summarized in a useful way for
    water managers?

18
Pennsylvania Water Resources Planning Act (Act
220)
  • Passed in 2002
  • Tasks include
  • Assess surface and groundwater resources
  • Assess existing and projected water use
  • Identify critical water planning areas
  • Create critical area resource plans

19
Screening Tool Development
  • Surface Water Availability
  • Determined by 7-Day, 10-Year low-flow statistic
    and net water use within a basin
  • Determined for approximately 10,000 watersheds
  • Pour points of watersheds colored to indicate
    water availability
  • PaDEP managers will be able to edit water use at
    pour points
  • Projected future demands
  • Requested water use
  • Supplemental water use data

20
Screening Tool Development
  • 3 Major Components
  • Hydrologic, statistical, and water-use data
  • Development of regression equations
  • Compilation of water use data
  • Spatial data elements for geographic analysis
  • GIS data preparation 10m DEMs
  • User system to access the water-planning
    information
  • Desktop application

21
Available Desktop Application Functions
  • Show Basin
  • Edit Basin
  • Fraction Supply
  • Recalc Selected Area
  • Save Scenario
  • Load Saved Scenario
  • Reload to Baseline
  • Recalc Entire

What do YOU think?
  • Will these tools help you?
  • What information do you need to understand and
    manage your States water availability?
