Resource Quality Characteristics

Resource quality = Characteristics

Resource Quality:

1. the quantity, pattern, timing, water level and assurance of instream flow;

2. the water quality, including the physical, chemical and biological characteristics of the water;

3. the character and condition of the instream and riparian habitat; and

4. the characteristics, condition and distribution of the aquatic biota.

Water Resource vs. Watercourse

Watercourse

• A river;

• A spring;

• A natural channel in which water flows regularly or intermittently;

• A wetland; lake or dam into which, or from which, water flows; and

• Any collection of water which the Minister may, by notice in the Gazette, declare to be a watercourse, and a reference to a watercourse include, where relevant, its bed and banks.

WETLANDS - Types

• Hydro geomorphic (HGM) classification system classifies wetlands according

– Form (geomorph-characteristics)

– The way in which water moves in, through and out of the wetland system (hydro-characteristics)

Floodplain

• HGM classification system recognises 5 generic palustrine wetland types, namely:

– Pans and depressions including lakes;

– Seepage wetlands;

– Unchannelled valley bottoms;

– Channeled valley bottoms; and

– Floodplains.

RATING CLASS MANAGEMENT DESCRIPTION

1 – 55 (L) Low Risk

Acceptable as is or consider requirement for mitigation. Impact to watercourses and resource quality small and easily mitigated. Wetlands may be excluded.

56 – 169 M) Moderate Risk

Risk and impact on watercourses are notably and require mitigation measures on a higher level, which costs more and require specialist input. Wetlands are excluded.

170 – 300 (H) High Risk

Always involves wetlands. Watercourse(s) impacts by the activity are such that they impose a long-term threat on a large scale and lowering of the Reserve.
