Editing text file in command line and make a new file

I have a big file look like the example:

chr1:16872433-16872504  54  112622
chr1:16872433-16872504  55  112110
chr1:16872433-16872504  56  110996
chr1:16872433-16872504  57  110306
chr1:16861773-16861845  20  38808
chr1:16861773-16861845  21  39768
chr1:16861773-16861845  22  40344
chr1:16861773-16861845  23  40637
chr1:16861773-16861845  24  41311
chr2:7990338-7990408    8   0
chr2:7990338-7990408    9   0
chr2:7990338-7990408    10  0
chr2:7990338-7990408    11  0
chr2:7990338-7990408    12  0

I want to extract every part starting with "chr1:16872433-16872504" and make a new .txt file. how can I do that in bash? I tried grep command but I do not know how to make it conditional.
