The Farm Dam Plugin was initially developed by Sinclair Knight Merz (SKM) and the Western Australian Department of Water (DoW), with support from the National Water Commission (NWC). Now this plugin is moved to the Core of the Source. The user can directly use its functionality without the farm dam plugin. For each dam, the Source conducts a water balance, including inflows, rainfall, evaporation, seepage, water usage (demand), and overflow (spill) components (Figure 1-1) in each time step. This means that, for each time step (e.g., a day), each water balance component is accounted for in Source for every farm dam modelled. For more information on the initial farm dam models, SKM has produced a series of project reports available upon request from the Department of Water. These reports include:

Some recorders for the farm dam in Source are described below to clarify the difference between the similar recorders.
Recorder | Description | Note |
Bypass Flow (ML/d) | The input parameter of the capacity of bypass in the current farm dam | |
Actual bypassed flows (ML) | The real bypass flows in the time step from the bypass way in the current farm dam | |
Interstation Flow Reference series (ML/d) | The input Reference data for Interstation Flow | |
Actual Interstation Flow (ML) | The real Interstation Flow in the time step to the current farm dam, and its value is the product of the Scaling Factor and Interstation Flow Reference series | |
Evapotranspiration (mm/d) | The input data of evapotranspiration from the current farm dam | |
Actual Evaporation Volume (ML) | The real evaporation volume in the time step from the current farm dam and its value is based on the dam surface area and inputted Evapotranspiration (mm/d) in the time step | |
Rainfall (mm/d) | The input data of rainfall to the current farm dam | |
Actual Rainfall Volume (ML) | The real rainfall volume in the time step to the current farm and its value is based on the dam surface area and inputted rainfall (mm/d) in the time step | |
SeepageTS (mm/d) | The input data of seepage from the current farm dam | |
Actual Seepage (ML) | The real seepage volume in the time step from the current farm dam and its value is based on the dam surface area and inputted SeepageTS (mm/d) in the time step | |
Demand Timeseries Value (ML/d) | The input template data of demand timeseries from the current farm dam | |
Actual Demand Volume (ML) | The real water volume is used for the demand in the time step from the current farm dam. its temporal distribution is determined by Demand Timeseries Value (ML/d) while its value can be different to Demand Timeseries Value (ML/d) | |
Diversion Fraction (%) | The input parameter defines how many percentages of the upstream flow will be directly diverted to the downstream flow. | |
Actual Diverted flows (ML/d) |
