The first step to finding an effective control method for this grass is to positively identify it. I would recommend taking a sample of the grass to your local USU County Extension office (2001 South State Street, Suite S-1200, (385) 468-4820) to get help identifying it. Based on your description, it may be annual bluegrass, but again, a positive identification is necessary. A resource for weed identification may also be accessed here:

Once you have identified the weed, you should consider a combination of control strategies including proper management of the desired grass, mechanical control of the weedy grass, and the use of appropriate herbicides should they be required. For annual bluegrass, a pre-emergent herbicide is recommended. Consult your Salt Lake County Extension office for a list of appropriate herbicides.

Best regards.
