Notes: 
Low water levels / shallow water depth 30 cm / dry conditions across site Several large patches of pond scum floating on surface - surprised to get low nutrient levels despite this observation? The tube did not quite fill up to half way mark for phosphate test; nearly half way instead - will this affect result greatly? Small herd of cattle in field and they use the pond
