集集共同引水工程計畫於90年完工，91年起集集攔河堰正式邁入營運階段，營運期間環境管理監測作業始自民國91年底至105年，為掌握水質狀況、水域生態環境變化情形及集集堰和斗六堰魚道使用效益，須持續辦理，為及早因應，掌握平時之變化，以維護營運期間之下游水域環境，延續營運期間環境監測工作，爰擬本計畫。 本案為環評承諾之延續性之必要計畫。

The Chi-chi collaborative water diversion plan has been approved and implemented since May 1993. Base on the evaluation through the environmental influence principle, the aforementioned plan has been considered as one of the major development project that required not only environmental monitoring during constructional stage, but also a properly formulated environment management plan throughout the operating stage. In 2002, the Chi-chi collaborative diversion plan had officially moved into its operational management stage. To continue with the environmental monitoring tasks and to research into the possible influences of this project to the surrounding areas, while come up with a counterplot to ease the negative influences, the Chi-chi weir has accomplished its environmental monitoring tasks between year 2003 and 2016. A follow up watershed dispersion and water quality control project continues in year 2017 in order to carry out the environmental protection policies.

本報告為「106年度斗六堰魚道功能監測及水域生態監測成果報告」，由經濟部水利署中區水資源局主辦，巨廷工程顧問股份有限公司執行。報告內容涵蓋斗六堰魚道功能監測及周邊水域生態監測，旨在評估魚道改修後的生物利用情形及生態廊道暢通性。 監測結果顯示，斗六堰魚道在大部分時間流量正常，但偶受豪雨或淤沙影響。水質方面，部分月份的生化需氧量、懸浮固體及大腸桿菌群等項目超出乙類水體標準。生態監測方面，記錄到多種台灣原生魚類及蝦類，其中大和沼蝦為優勢蝦種。報告指出，斗六堰魚道效益良好，對生態廊道有正面助益，且周邊生物多樣性豐富。報告也提及何氏棘?的族群擴張及其對原生種的影響，並分析了歷年生物族群的趨勢變化。
