We present results on our efforts to measure total star-formation rates (SFRs) for a sample of 471 0.05 < z < 0.09 galaxy clusters drawn from the C4 catalog. The C4 catalog is a spectroscopic and color-selected cluster sample selected from the Sloan Digital Sky Survey. We investigate how the total SFR, the fraction of star-forming galaxies, and the average SFR per stellar mass depend on cluster mass, redshift, and substructure. The C4 cluster sample provides an ideal low-redshift benchmark for cluster evolution studies. Characterizing cluster star formation properties in terms of the total SFR per cluster mass, we compare the C4 clusters to published Hα surveys for higher redshift (0.2 < z < 0.85) clusters.
