The Water Resources Agency (WRA), MOEA has continually conducted investigations of the current status of rivers between 2002 to 2022 and has completed the investigation of 26 rivers. Include water area survey(fish, shrimps, crabs, aquatic insects, Annelid, algae, aquatic plants) and land area survey near the river(terrestrial plants, birds, amphibians, reptiles, mammals), analyze the river ecology and environmental quality. 本河川情勢調查資料集是經濟部水利署自2002至2022年期間之河川生物調查資料，包含水域（魚、蝦蟹、水生昆蟲、螺貝類、藻類水生植物）及臨近河川之陸域（陸域植物、鳥、兩棲類、爬蟲類、哺乳類）之生物調查資料。
Sampling Description
Study Extent
Taiwan台灣（包含24條中央管河川及2條跨縣市河川）。Sampling
Electric fishing, shrimp pots, hand-throwing nets, Surber net sampler, crossing lines, the circle method 電氣採捕, 蝦籠, 手拋網, 蘇伯氏水網, 穿越線, 圓圈法Method steps
- ●電氣法：努力量單元為距離，以50公尺距離為一個單元，每個樣站調查2個單元(或以上)。調查區域需包含可涉水水域且中低流速的環境型態。 ●蝦籠法：努力量單元為籠具數量，每個籠具為一個單元，每個樣站調查3個單元，調查需隔夜，且需以餌料進行誘集。餌料可用自製或市面上可買到的香餌或生鮮等。調查區域合適用於可涉水水域且中低流速的區域，但需要固定。深水區或流速較快區域可用引繩與固定物方式進行。 ●定面積採集法(蘇伯氏水網)：採集次數，固定面積(50公分見方網格)每網次採集為一個單元，每個樣站不重複點位採集3網次。可涉水水域且中低流速的區域。 ●手拋網：每網次為一個單元，每個樣站不重複點位採集3網次。 ●穿越線法：須鄰近範圍內各類型重要的鳥類棲地，穿越線長度為1,000公尺，樣點間距為200公尺，總計設置6個相距200公尺的樣點。 ●圓圈法：每個樣區設置6–10個調查樣點， 每年於鳥類繁殖季期間（三到六月）進行兩次晨間調查。
