研究了亚利桑那州Verde河上的马蹄-巴特利特供水水库系统，以确定水文变异对流域溶解有机碳（DOC）输出和水库系统内DOC生产的影响。在春季融雪和夏末季风性降雨期间，DOC浓度较高。Verde河流域DOC装载（每月公斤）的大部分（~ 90%）发生在春季。细菌对DOC的消耗和藻类对DOC的产生改变了水库中DOC的化学特征。1998 - 1999年，当水通过Horseshoe‐Bartlett水库系统时，DOC的负荷量减少了21% - 38%，卤乙酸前体负荷量减少了30% - 45%。根据年度水文模式和水库运行情况，马蹄-巴特利特水库系统既可以产生DOC，也可以消耗DOC。
The Horseshoe‐Bartlett water supply reservoir system on the Verde River in Arizona was studied to determine the impact of hydrologic variability on dissolved organic carbon (DOC) export from the watershed and DOC production within the reservoir system. High DOC concentrations occurred during spring snowmelt and late summer monsoon rains. The majority (∼90%) of DOC loading (kilograms per month) from the Verde River watershed occurred in the spring. Bacterial consumption and algal production of DOC changed the chemical characteristics of DOC in the reservoir. DOC loading was reduced by 21 to 38%, and haloacetic acid precursor loading was reduced by 30 to 45% as water passed through the Horseshoe‐Bartlett reservoir system in 1998–99. Depending on annual hydrologic patterns and reservoir operation, the Horseshoe‐Bartlett reservoir system can either produce or consume DOC.
