The results of recent experiments of water pressure broadened by $O2$, $N2$, He, and $H2$ will be presented. The $31,3-220$ and $41,4-32,1$ transitions of water ($H2O$) were studied between 80 K and 600 K. Results for the temperature dependence of the pressure broadening parameters are compared with predictions from theory and with previous experimental results. Low temperature measurements were made in a collisionally cooled $cell1$ with a continuously variable temperature between 80 K and 300 K. Static measurements were made in a quartz cell enclosed in an oven with a continuously variable temperature between 80 K and 600 K. $\mathrm{<mrow\; data-mjx-texclass="ORD">1</mrow>}$ T.M.
