About this gauge's record

This site's drainage basin covers approximately 247 sq mi of contributing watershed. USACE's continuous elevation record for this project begins in 1980 (3 tracked series for this project).

The dam behind Lake Georgetown

Lake Georgetown is held back by North San Gabriel Dam (also recorded as Lake Georgetown; North Fork Dam) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 162 ft high and running 6,650 ft along its crest , built across NORTH FORK SAN GABRIEL RIVER in Williamson County , near GEORGETOWN . It was completed in 1980 , and is owned by USACE - Fort Worth District (a federal owner) , to a design credited to CESWF.

Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain . It also serves flood risk reduction;fish and wildlife pond;recreation;water supply.

It is founded on rock;soil, with a earth core. Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. The spillway opening is 1,000 ft wide. Its outlet works use uncontrolled0.

NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in.

At its normal pool the reservoir covers about 1,310 acres. NID records a maximum storage of 236,500 acre-ft against a normal storage of 37,100 acre-ft. Its maximum discharge capacity is 342,000 cubic feet per second.
