purchase and/or upgrading of equipment for detection, identification and intervention at the borders (e.g. vehicles, vessels, aircraft, helicopters, sensors, cameras, etc.), provided the need for this equipment has been clearly identified at European level.

limited navigation (loss making journeys which are not economically justified) during insufficient navigation conditions (the level of water below 200 cm, i.e. below 140 cm of the vessels’ draught) and no navigation (the level of water below 170 cm, i.e. below 110 cm of the vessels’ draught).

Therefore, an extremely high degree of systems integration is needed between sensors and the algorithms that actually do the battle management right through that whole chain.

Physical Change Upstream Drawdown -reduced littoral productivity -reduced littoral spawning success -reduced tributary access -reduced water quality Impoundment -reduced dissolved oxygen -settling of suspended sediment Downstream Reduced flow -reduced habitat quantity -altered water temperature Inadequate flushing flow -accumulation of fine sediments in gravel substrate -changes in stream morphology Increased flows -scouring of substrates -physical displacement of fish -destabilization of stream banks Rapid flow fluctuation -displacement and stranding of fish and exposure of eggs Flow diversion -disruption of fish homing to natal streams ...[+++] Altered temperature -altered habitat quality regime -altered benthic productivity Altered water quality -altered benthic productivity Elevated total gas -injury or death of fish due to gaspressure bubble disease The majority of B.C. Hydro projects were undertaken many years ago.

The Atlantic Salmon Federation is dedicated to the attainment of the following goals: maximizing survival of the wild Atlantic salmon; ensuring a healthy freshwater environment for wild Atlantic salmon; ensuring a healthy ocean environment for wild Atlantic salmon; optimizing the number of wild salmon spawning in their native rivers; and optimizing the survival of wild salmon in the fresh water and sea ecosystems.

However, this rationalisation of the water legislation would not lead to a lowering of the existing level of environmental protection; indeed the level of ambition would be raised and the efficiency of the environmental protection measures increased: - Water quantity objectives would be included alongside water quality to ensure water abstraction does not lead to shortages and/or environmental damage.
