Milagro is a water Cherenkov extensive air shower array that continuously monitors the entire overhead sky in the TeV energy band. In this paper the results from an analysis of ˜3 years of data (12/15/2000-11/25/2003) are presented. The data has been searched for steady point sources of TeV gamma rays. Two sources are detected, the Crab Nebula and the active galaxy Mrk 421. For the remainder of the Northern hemisphere we set 95% C.L upper limits between 275 and 600 mCrab (4.8-10.5×1012 cm-2s-1) above 1 TeV, for source declinations between 5 degrees and 70 degree. The sensitivity of Milagro depends upon the spectrum of the source at the top of the atmosphere, therefore the dependence of the limits on the spectrum of a candidate source are presented. Because high-energy gamma rays are absorbed by interactions with the extragalactic background light we give the dependence of the flux limits on the redshift of a candidate source. The upper limits presented here are over an order of magnitude more stringent than previously published limits from TeV gamma-ray all-sky surveys.
