9月份見識之旅活動，於2020年9月19日由呂明澐小姐帶領13位祐生見習生及家長們，進行台南曾文水庫生態暨水資源環教之旅。活動開始之初，領隊呂明澐小姐提醒本次活動注意事項及觀察重點，先行建立見習生的背景知識。
For the study tour of September 19, 2020, Ms. Lu Ming-yun led 13 ARF interns and their parents on a trip to Tainan Zengwen Reservoir to learn about ecology and water resources. At the start of the day's activities, team leader Ms. Lu Ming-yun reminded everyone about things to note and what to observe, and gave the interns some background knowledge.
本次行程以參訪曾文水庫為主軸。行程一開始即搭船進行遊湖導覽，導覽人員首先介紹水庫位址及周邊環境，指出曾文水庫位於嘉南二個縣市的交界處，大部分面積在嘉義縣大埔鄉，僅10%位於台南市楠西區，是全台最大的水庫與人工湖泊。接著說明水域上大壩閘門、泥沙自動監測儀及抽砂清淤平台等設施如何維持水庫正常運作，並提及當年莫拉克颱風帶來的強烈衝擊。隨後行船至山豬島，島上的野生山豬無人飼養，是以未開放登島，僅能在港口上觀賞或餵食工作人員提供的飼料，導覽人員亦提醒眾人切勿過於靠近，以免發生危險。遊湖行程最後一站來到飛鷹峽谷，兩旁山壁高聳、老鷹在此築巢而得名，一年之中，只在夏季豐水期高水位時船隻才能駛入，參訪當日有幸窺得一隻老鷹於高空盤旋。
The focus of the study tour is Zengwen Reservoir. The tour starts at the pier where everyone takes a boat ride on the reservoir. Introducing the reservoir location and surrounding environment, the tour guide pointed out that Zengwen Reservoir is located in the intersection between Chiayi and Tainan. A larger part of the reservoir lies within Dapu Township, Chiayi County, and only 10% lies within Nansi District in Tainan City, making it the largest reservoir and man-made lake in Taiwan. The tour guide continued to explain the workings of dam gates, automatic sediment monitoring system and dredging barge. He further mentioned that when Typhoon Morakot swept through Taiwan, its forceful impact on the reservoir. When the boat reached Wild Boar Island, everyone could watch the wild boars from the pier and feed them with fodder provided by the tour guide but had to stay off the island as the wild boars are not domesticated. The tour guide also warned everyone to keep their distance for safety reasons. The last stop of the lake tour was the Eagle Valley, which derives its name from the towering cliffs on both sides and eagles nesting there. Boats can only travel into the valley in summer when the reservoir water level is high. On the day of the tour, everyone was lucky to spot an eagle circling around the sky.
下午前往永續利用館進行水庫生態環教課程，由南水局副工程司洪素球女士擔任導覽老師。課程一開始即說明水庫選擇壩址須考量的因素，曾文水庫位處山谷地形適合蓄水，加上周圍有阿里山、玉山等山脈及曾文溪之水源匯流至此，強調水資源與環境氣候、地文、水文、生態和人文永續發展的關係，更提醒眾人愛護水資源的重要性。隨後導覽老師講述水庫周遭森林因人跡罕至，生態結構未受破壞，有許多保育類動物在此活動，並播放紅外線相機拍攝之影片，介紹其特徵與習性。緊接著進行尋寶遊戲，導覽老師首先以氣味與外形讓見習生記住大致特徵，分組尋找印象中的香草植物，後公布名稱並說明特徵用途，讓見習生更加認識各種香草。遊戲結束後來到曾文之眼尋找五色鳥的家，導覽老師解釋五色鳥會在叢林的枯樹幹上啄洞築巢，又名台灣擬啄木，並帶領眾人尋找樹洞蹤跡與觀察特徵。至此，本日活動已近尾聲，大家一起合照留念後搭車返程，並期待於下次見識之旅再相見。
In the afternoon, everyone proceeded to Sustainable Utilization Center to learned about reservoir ecology from Ms. Hung Su-chiu, assistant engineer with the Southern Region Water Resources Office. The lesson started with factors that should be considered when choosing a location for the reservoir dam. Due to its valley terrain, and being surrounded by mountains like Alishan and Yushan, and a catchment area for Zengwen River, Zengwen Reservoir is highly suitable for holding water. Ms. Hung also emphasized on the relationship between water resources and sustainability of climate, topography, hydrology, ecology and human culture, and reminded everyone the importance of protecting water resources. Ms. Hung went on to say that there are many protected animals in the forest surrounding the reservoir as its ecological structure is undamaged due to absence of human intervention. She also played videos recorded using infrared cameras while explaining the characteristics and habits of these animals. During the treasure hunt game that followed, the interns were told to remember certain scents and appearances, and then divide into teams to search for the correct herbs in the garden. The name and usage of the herbs were eventually announced and it allowed the interns to learn more about various herbs. After the game ended, everyone went to the Eye of Zengwen to look for the home of the Taiwan barbet. Ms. Hung explained that the Taiwan barbet likes to nest in tree cavities, and proceeded to bring everyone to look for signs of tree cavities and observe their characteristics. At this point, the day's itinerary came to an end. Everyone took a group photo before heading back and looked forward to the next study tour.
