Introduction

As resource demands and pressure increases so to do the requirements of both management and information needs. Outlined below are the key issues facing the region as determined by the State / Territory water management agency.

What is the estimated demand for surface water in Gordon River?

How was this assessment undertaken in the Gordon River Surface Water Management Area?

Development Potential:

This SWMA has reached its likely full development potential. Water not currently used for power generation purposes is now utilised by the environment and is unlikely to be used for other purposes with the possible exception of some very small domestic use.

Estimated Use:

Not applicable - no increase forcast.

Management goals and objectives:

1 Essential needs of town water supplies and stock and domestic needs, 2 Ecosystem needs.

3. Water for Hydro Electric Corporatin, 4 Supply of water for irrigation and non essential town supply purposes eg parks and gardens,

See TAS Water Resources Assessment 2000 Report and Water Resources Assessment 2000 Technical Report for comment on methods and assumptions.

Comments on Management Responses in the Gordon River Surface Water Management Area

Current Management Response:

Desired (Current) Management Response:

2020 Management Response:

Not applicable

2050 Management Response:

Not applicable

See TAS Water Resources Assessment 2000 Report for comment on management responses.

Assessment of Monitoring

Efficacy of the network:

Not applicable

Data management requirements:

Not applicable.

Protective management:

Current methods used in relation to these catchments should be satisfactory. Methods allow for assessment of current arrangements and for these to be modified as required

Options for monitoring:

Not applicable.

See TAS Water Resources Assessment 2000 Technical Report for an assessment of monitoring

Data Availability, Gaps and Recommendations

Data Availability:

There are stream gauging stations on the Gordon, Franklin and Collingwood rivers.

Current Gaps and Recommendations:

Data Gaps: The following have been identified as gaps in data:

1. Assumptions used in Review 85 for determining divertible yield;

2. No yield for HEC system available

3. Information on sustainable yield not available;

4. Salinity data

5. No natural mean annual flow available.

Recommendations:

1. Re estimate divertible and developed yield for the SWMA.

2. Estimate sustainable yield for SWMA.

3. Review and where appropriate ugrade water quality monitoring stations.

Future Gaps:

In relation to Project 2 no gaps have been identified.

See TAS Water Resources Assessment 2000 Technical Report for a review of data availability,gaps and recommendations.
