39°42′31″N 115°55′10″E / 39.7084906°N 115.9195748°E / 39.7084906; 115.9195748 大石河,又称琉璃河[1][2]北京地区的一条河流,为拒马河的支流。全长129公里,流域面积1280平方公里。

位于房山区境内。发源于房山区霞云岭乡堂上村,流经9个乡镇后汇入北拒马河。以青龙湖镇漫水河水文站(辛开口)为界,以上为山区河道,长87.6km。

主要支流有

  • 周口店河:流域面积80km2,长度20.2km
  • 挟括河:流域面积150km2,长度32.1km
  • 牤牛河:流域面积65km2,长度23.8km
  • 丁家洼河:流域面积25km2,长度11.8km
  • 东沙河:流域面积19km2,长度7.4km
  • 西沙河:流域面积11km2,长度8km
  • 马刨泉河:流域面积27km2,长度14.4km

1958年后,在流域内修建了鸽子台水库、大窖水库(总库容55万立方米)、牛口峪水库、丁家洼水库(总库容110万立方米,其中防洪库容48万立方米)、天开水库

历史上,1939年、1956年、1963年、1996年、2012年、2023年均发生严重流域洪水。大石河干流无控制性工程,规划在佛子庄乡的干流河道建设二道河水库,总库容7514m3;在大件路以上的大石河河滩规划通过开挖砂砾料建设“大石河滞洪水库”,总库容约3000万3,下游平原河道可由防御二十年一遇提高到五十年一遇洪水。
