小峰水庫建成后運行初期(qi)，由于受經濟和技術(shu)條件(jian)的限(xian)制，工程(cheng)(cheng)建設(she)標(biao)準低，工程(cheng)(cheng)存在著(zhu)質量較差(cha)、病險隱患多等工程(cheng)(cheng)安全問題，被(bei)迫降低水位進行運行。為了確保人民生命財產(chan)安全，發揮水庫最(zui)大效益，自(zi)1992年開(kai)始，按設(she)計要(yao)求對(dui)水庫主體工程(cheng)(cheng)已(yi)進行2次(ci)全面除(chu)險加固(gu)，累(lei)計投入除(chu)險加固(gu)資金6230萬(wan)元。 ? ? ? ? ? ? ? ?

第一次(ci)除險(xian)加(jia)固(gu)(gu)工(gong)程(cheng)于1992年(nian)動(dong)工(gong)，1999年(nian)完(wan)工(gong)。工(gong)程(cheng)項目(mu)主(zhu)(zhu)要是加(jia)固(gu)(gu)主(zhu)(zhu)壩(ba)基礎、溢(yi)洪(hong)道出(chu)口段(duan)及修(xiu)建(jian)進(jin)庫(ku)公路，投資1853.00萬元；第二(er)次(ci)除險(xian)加(jia)固(gu)(gu)工(gong)程(cheng)于2002年(nian)動(dong)工(gong)，2004年(nian)1月完(wan)工(gong)，工(gong)程(cheng)主(zhu)(zhu)要項目(mu)有主(zhu)(zhu)壩(ba)副(fu)壩(ba)壩(ba)體防滲，主(zhu)(zhu)壩(ba)右壩(ba)肩(jian)培厚，大(da)壩(ba)安全監測，溢(yi)洪(hong)道、主(zhu)(zhu)壩(ba)副(fu)壩(ba)壩(ba)體加(jia)固(gu)(gu)，副(fu)壩(ba)防汛(xun)道路建(jian)設等工(gong)程(cheng)，完(wan)成(cheng)投資4252.00萬元。經過2次(ci)維修(xiu)加(jia)固(gu)(gu)后，已基本消除工(gong)程(cheng)隱(yin)患，大(da)大(da)提高(gao)了水庫(ku)的防汛(xun)能(neng)力(li)和蓄水能(neng)力(li)。

小峰(feng)水(shui)庫建成后，發揮了水(shui)庫防(fang)洪、供水(shui)、灌溉和發電等多方面的作用，具有(you)顯(xian)著的經濟(ji)效益(yi)和社會效益(yi)。

洪(hong)(hong)方(fang)面。汛前騰空(kong)水(shui)(shui)庫(ku)，預留防(fang)(fang)洪(hong)(hong)庫(ku)容，發揮水(shui)(shui)庫(ku)蓄洪(hong)(hong)、調節(jie)洪(hong)(hong)峰的功(gong)能，提高水(shui)(shui)庫(ku)下游(you)防(fang)(fang)城(cheng)江沿(yan)岸鄉鎮的防(fang)(fang)洪(hong)(hong)能力，把洪(hong)(hong)澇災(zai)害損失降到最低限度。

供(gong)水(shui)(shui)灌(guan)溉方面。由于防城江來(lai)水(shui)(shui)豐枯(ku)不均，且相差懸殊，利用水(shui)(shui)庫(ku)蓄水(shui)(shui)每年可增(zeng)加(jia)7820萬立方米的調節水(shui)(shui)量，以(yi)(yi)豐補枯(ku)進行調節，大(da)(da)大(da)(da)提高了防城港市城區工業和(he)生活用水(shui)(shui)的供(gong)水(shui)(shui)能力；同時(shi)，可以(yi)(yi)擴(kuo)大(da)(da)和(he)改善農田灌(guan)溉面積18.38萬畝。

發(fa)電(dian)(dian)(dian)方(fang)面(mian)。已建(jian)成梯級水電(dian)(dian)(dian)站(zhan)(zhan)(zhan)小峰水電(dian)(dian)(dian)站(zhan)(zhan)(zhan)和江口水電(dian)(dian)(dian)站(zhan)(zhan)(zhan)2座，總裝機容量5350千(qian)瓦，年均發(fa)電(dian)(dian)(dian)量2116萬千(qian)瓦小時，水庫(ku)為(wei)多年調節水庫(ku)，水電(dian)(dian)(dian)站(zhan)(zhan)(zhan)可(ke)承擔防(fang)城電(dian)(dian)(dian)網的部分調峰任務，緩解電(dian)(dian)(dian)網峰谷矛盾和電(dian)(dian)(dian)力供需(xu)矛盾，為(wei)促(cu)進地方(fang)經濟(ji)發(fa)展(zhan)發(fa)揮了積極作(zuo)用(yong)。
