于橋水(shui)庫位于天津市薊(ji)縣城(cheng)東，是國家重點大型水(shui)庫之一，水(shui)庫壩址(zhi)建于薊(ji)運河(he)左支(zhi)流(liu)州河(he)出口處。
控制流域面積2060 k㎡，占整個(ge)州(zhou)河(he)流域面積的(de)96%。州(zhou)河(he)由沙河(he)、淋河(he)、黎(li)河(he)三大(da)支流匯(hui)合而成(cheng)，各支流上游溝澗甚多(duo)，支流分散成(cheng)輻射狀(zhuang)匯(hui)集于(yu)(yu)州(zhou)河(he)盆(pen)地(di)，水庫庫區即位于(yu)(yu)該盆(pen)地(di)，最(zui)大(da)回(hui)水長東西約(yue)30km，南北(bei)寬8km，最(zui)大(da)淹(yan)沒面積250k㎡（正常蓄(xu)水位時淹(yan)沒面積86.8 k㎡）。州(zhou)河(he)流域境內雨(yu)(yu)量充沛，多(duo)年(nian)平(ping)均(jun)降雨(yu)(yu)750mm，多(duo)年(nian)平(ping)均(jun)徑流量5.06億m3。水庫運用初期，曾出現過壩(ba)下(xia)游大(da)面積沼澤化(hua)、管(guan)涌等(deng)現象，唐山大(da)地(di)震后，主河(he)床(chuang)附近壩(ba)段壩(ba)坡(po)腳產生裂縫，壩(ba)基出現砂層(ceng)液化(hua)現象。

風光特產
風景秀麗、群山(shan)環繞的于橋水庫坐(zuo)落在(zai)薊縣(xian)城東，又名(ming)翠屏(ping)(ping)湖(hu)，因南依翠屏(ping)(ping)山(shan)而得名(ming)。翠屏(ping)(ping)湖(hu)水面(mian)寬(kuan)闊，東西(xi)長30公里，南北(bei)最寬(kuan)處(chu)15公里。登翠屏(ping)(ping)山(shan)俯(fu)瞰(kan)，煙波浩淼，水天一(yi)(yi)色；蕩舟湖(hu)上，鷗(ou)浮(fu)(fu)上下，魚戲東西(xi)。南岸的翠屏(ping)(ping)山(shan)綠樹成蔭(yin)，花果(guo)滿(man)園，葡(pu)萄壓枝(zhi)。象一(yi)(yi)幅五彩斑(ban)斕的畫(hua)卷(juan)。北(bei)岸山(shan)中古(gu)松蒼勁挺拔，建筑鱗(lin)次櫛比，層次豐富多(duo)變。西(xi)岸大(da)堤(di)橫臥，綠樹緣堤(di)，遠山(shan)如(ru)黛(dai)，云煙飄(piao)浮(fu)(fu)，極(ji)盡幻(huan)變幽深(shen)之趣。翠屏(ping)(ping)湖(hu)盛(sheng)產魚蝦(xia)，尤以金翅鯉魚聞名(ming)天下，據《薊縣(xian)志》載：“鯉魚產于薊運河者皆金鱗(lin)赭(zhe)尾。”而今(jin)這種曾為(wei)(wei)皇帝貢品的“御膳鯉”巳(si)成為(wei)(wei)普通游(you)人的盤(pan)中珍(zhen)品。
翠(cui)(cui)屏(ping)(ping)湖(hu)(hu)夏季氣候涼爽，是理想(xiang)的(de)(de)避(bi)暑(shu)勝地(di)。盛夏炎炎，眺(tiao)翠(cui)(cui)亭旁的(de)(de)平灘上(shang)，一群(qun)群(qun)穿著(zhu)游泳(yong)衣的(de)(de)游人或坐或臥，悠然自得(de)地(di)沐浴著(zhu)陽光，人們紛紛下(xia)水(shui)游泳(yong)，任涼爽的(de)(de)湖(hu)(hu)水(shui)沖散暑(shu)熱(re)。水(shui)中魚(yu)蝦避(bi)開了(le)暢游的(de)(de)人群(qun)，往來(lai)(lai)于紅(hong)蕖綠(lv)草之(zhi)間，招來(lai)(lai)了(le)萬(wan)(wan)釣千竿。冬天，這里是滑冰(bing)、賞雪的(de)(de)理想(xiang)場所。整個翠(cui)(cui)屏(ping)(ping)湖(hu)(hu)雪蓋冰(bing)封，銀裝(zhuang)素裹，滑冰(bing)愛(ai)好者紛至沓來(lai)(lai)。翠(cui)(cui)屏(ping)(ping)湖(hu)(hu)南(nan)岸多(duo)農(nong)家院旅店(dian)及(ji)活魚(yu)館，是都(dou)市人周末節(jie)假的(de)(de)絕佳(jia)去處。水(shui)質優良(liang)的(de)(de)翠(cui)(cui)屏(ping)(ping)湖(hu)(hu)湖(hu)(hu)域內有(you)120多(duo)種鳥類(lei)。每(mei)年4月初(chu)，水(shui)鳥多(duo)達2萬(wan)(wan)多(duo)只(zhi)，其(qi)中有(you)被國家列為(wei)重(zhong)點保(bao)護的(de)(de)大天鵝、白(bai)鸛、白(bai)琵鷺等八(ba)種珍禽。
