The source of the water from a river/channel is recorded as (from), its storage into a holding reservoir, lake or dam is recorded as (into), then its final destination to a town or township is recorded as (to). Diversion also means the storage of water in an onstream reservoir from its inflowing streams.

fisheries regulationsrestrictions on fishing activities imposed by state governments and enforceable under various acts. Some have been included in this publication to make anglers aware that restrictions exist and also to inform those anglers that do not require a fishing licence that they are still subject to such regulations. These regulations were correct as at September 2002 but it is the angler's responsibility to ensure they are aware of the current and complete list of fishing regulations.
fishwaya construction or modification to a barrier which enables fish to pass either upstream and/or downstream. A vertical slot fishway consists of a series of usually concrete boxes which ascend the barrier in a ladder form. The entry and exit openings to each box are narrow vertical slits which are offset to the extreme right and left and act as baffles to the flow, creating turbulence and areas of low velocity water within each box and at each entrance into the next box. Rock ramps are built by constructing a ramp of rubble through which water flows providing a series of small pools where fish can rest as they move up or down the ramp. They are usually installed for migration of small-sized fish which have some climbing ability.
