Os indicadores analisados foram: a) Razão Global de Consumo (RGC) e Razão de Consumo do Lote (RCL), as quais representam as relações entre o somatório dos volumes de água, correspondentes às necessidades hídricas das culturas existentes no perímetro ou no lote e o volume de água captada do rio ou reservatório; b) Razão de Consumo Médio (RCM) que compreende o consumo de água médio por unidade de superfície irrigada no sistema. A RGC quando analisada no período anual, apresenta os valores de 0,91 e 0,99 relativos ao biênio 2008/2009, respectivamente, dentro da faixa operacional requerida que é de 0,70 – 1,00; porém, quando analisada mensalmente, o perímetro em geral apresenta índices que estão fora da faixa aceitável que seria de 0,60 – 1,10. No setor de empresas, valores de 0,83 e 0,97 e os índices de RCL calculados para os setores de pequenos produtores, no ano de 2008, apresentaram valores acima do limite superior da faixa aceitável. Do período de 2004 – 2010, a Razão de Consumo Médio (RCM) mensal no período foi de 1500 m³ ha^-1, verifica-se que os valores médios acima do planejado encontram-se inseridos nos meses de agosto a novembro. </span><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves /> <w:TrackFormatting /> <w:HyphenationZone>21</w:HyphenationZone>
