Many nmr solvent peak lists are very useful but not complete. I usually just refer to the J.Org.Chem article by Gottlieb et al. for solvent peaks, the corresponding chemical shifts for water and other commonly used solvents) - but DMF is not on that list as a solvent. A quick googling returned this list:NMR-Lösungsmittel. The introductory text is in German, and translates as:
br = broad signal, m = fine structure of peaks
*water peaks* depending on concentration and polarity of the dissolved compounds the water peaks may be shifted a bit; temperature differences also influence the chemical shift of water. All 1H-spectra show a broad water peak as a result of atmospheric humidity - usually this peak is neglectable, but in very dilute solutions your integrals may be affected
this is the Google search, resulting in another good table, another one, and many more
