Faint star-forming galaxies at $$z\sim 2-3$$ can be used as alternative background sources to probe the Lyman-α forest in addition to quasars, yielding high sightline densities that enable 3D tomographic reconstruction of the foreground absorption field. Here, we present the first data release from the COSMOS Lyman-Alpha Mapping And Mapping Observations (CLAMATO) Survey, which was conducted with the LRIS spectrograph on the Keck-I telescope. Over an observational footprint of 0.157$$\mathrm{deg}^2$$ within the COSMOS field, we used 240 galaxies and quasars at 2.17
