Water Resource Management & Flow Regulation


novar fishings, river alness, loch morie damThe dam (& fish pass) on the outflow of Loch Morie was constructed in 1978 by Novar Estate for river regulation, specifically to benefit the fishery.

The goal of current management practices is the optimal use of water resources and flow regulation to enable the completions of all life history stages of salmonids. This provides an important benefit to the fishery in terms of stocks.

As a by-product river regulation also generally results in improved angling opportunities e.g. raising river water levels to enable the free migration of salmon through the river will generally improve fishing prospects.

Current management practices include:

Flow Rate & Water Level Monitoring
River flow rates (water levels) and loch levels are monitored throughout the year to ensure optimum application of other management practices.

Compensation Flow
Subject to loch reserves, minimum flow rates are provided throughout the year for the survival of adult and juvenile salmon and at specific times to keep spawning gravels and nursery habitat wetted. Enhanced flow rates are provided where possible throughout the summer to aid the migration of adult salmon.

Occasional freshets are provided as required and subject to reservoir reserves to encourage the migration of grilse and salmon, particularly when they become trapped at migration obstacles.

Loch Level Management
River flow levels are also regulated at certain times of year and during spates to allow loch reserves to build up.
