小峰水(shui)庫(ku)(ku)建成后運行初期，由于受經濟和技術條件的(de)限制，工(gong)程(cheng)建設(she)標準(zhun)低，工(gong)程(cheng)存(cun)在著質量較差、病險(xian)隱患多等(deng)工(gong)程(cheng)安(an)全(quan)問題，被迫(po)降低水(shui)位進行運行。為(wei)了確保(bao)人民生命財產安(an)全(quan)，發(fa)揮水(shui)庫(ku)(ku)最大(da)效益，自1992年開始，按設(she)計要求對(dui)水(shui)庫(ku)(ku)主體(ti)工(gong)程(cheng)已進行2次全(quan)面除(chu)險(xian)加(jia)固，累(lei)計投(tou)入除(chu)險(xian)加(jia)固資金6230萬元。 ? ? ? ? ? ? ? ?

第(di)一次(ci)除險加(jia)固(gu)工程(cheng)(cheng)于1992年動(dong)工，1999年完工。工程(cheng)(cheng)項目主(zhu)(zhu)(zhu)要是加(jia)固(gu)主(zhu)(zhu)(zhu)壩基礎(chu)、溢洪道(dao)出口段及修建(jian)進庫公(gong)路，投資(zi)1853.00萬(wan)元；第(di)二次(ci)除險加(jia)固(gu)工程(cheng)(cheng)于2002年動(dong)工，2004年1月完工，工程(cheng)(cheng)主(zhu)(zhu)(zhu)要項目有主(zhu)(zhu)(zhu)壩副(fu)壩壩體(ti)防滲，主(zhu)(zhu)(zhu)壩右(you)壩肩培厚，大壩安全監測，溢洪道(dao)、主(zhu)(zhu)(zhu)壩副(fu)壩壩體(ti)加(jia)固(gu)，副(fu)壩防汛道(dao)路建(jian)設等工程(cheng)(cheng)，完成投資(zi)4252.00萬(wan)元。經過2次(ci)維(wei)修加(jia)固(gu)后(hou)，已基本消除工程(cheng)(cheng)隱患，大大提高了水庫的防汛能(neng)力和蓄水能(neng)力。

小(xiao)峰水(shui)庫(ku)(ku)建成后，發(fa)揮(hui)了水(shui)庫(ku)(ku)防洪(hong)、供(gong)水(shui)、灌溉和發(fa)電(dian)等多方(fang)面的(de)作用(yong)，具有顯著的(de)經濟效益(yi)(yi)和社會效益(yi)(yi)。

洪(hong)(hong)方(fang)面。汛前騰空水(shui)庫(ku)，預留防(fang)洪(hong)(hong)庫(ku)容，發揮水(shui)庫(ku)蓄洪(hong)(hong)、調節洪(hong)(hong)峰的功能，提高(gao)水(shui)庫(ku)下游(you)防(fang)城江沿岸鄉鎮的防(fang)洪(hong)(hong)能力，把洪(hong)(hong)澇災害(hai)損失(shi)降(jiang)到最低(di)限度(du)。

供水(shui)灌溉方(fang)面。由(you)于防城(cheng)江來水(shui)豐枯不(bu)均，且(qie)相差懸殊，利用水(shui)庫(ku)蓄(xu)水(shui)每年可(ke)增加(jia)7820萬立(li)方(fang)米的調節(jie)水(shui)量(liang)，以豐補枯進行(xing)調節(jie)，大(da)大(da)提高了防城(cheng)港市(shi)城(cheng)區(qu)工(gong)業和(he)生活用水(shui)的供水(shui)能(neng)力；同(tong)時，可(ke)以擴大(da)和(he)改善(shan)農田灌溉面積18.38萬畝。

發電方面。已建(jian)成梯級水(shui)(shui)電站小峰(feng)水(shui)(shui)電站和(he)江(jiang)口水(shui)(shui)電站2座，總裝(zhuang)機容(rong)量5350千(qian)瓦，年均發電量2116萬千(qian)瓦小時，水(shui)(shui)庫(ku)為多(duo)年調節水(shui)(shui)庫(ku)，水(shui)(shui)電站可承擔防城(cheng)電網(wang)的部分(fen)調峰(feng)任務，緩(huan)解電網(wang)峰(feng)谷矛盾(dun)和(he)電力供需(xu)矛盾(dun)，為促進地(di)方經濟(ji)發展(zhan)發揮(hui)了積極作用。
