How to get water to settle?

You'll need to explore regrading your yard, installing a sufficient French drain system with adequate degree of slope to the trench and the drain piping, checking gutters and downspouts for leaks and repair/replace, insuring all downspouts deposit water at least 10' away from your home's foundation. When doing the last suggestion, it's better to run the downspout underground, on a slope, then "daylight" the water closer to the front of your property.

Without a photo, it sounds like you need to regrade the yard and / or install a French drain system. Have a few consults with reputable landscape architects or designers to see what the best cause of action would be. If you decide to hire out, here is how to hire any contractor.

Directing downspouts away from the house and adding drain system may be necessary.

Thank you all for the good advice

but it not a big yard. I will see what I

can do. Thank you all

Since it's not a big yard you should be able to see where the water comes from. It could be coming from your roof, or it could be coming from your neighbor's yards. You might be near the bottom of a long drainage area for several yards. When it's raining look out the window and make note of where any flowing water comes from. What type of soil do you have? Clay soil drains slowly. If you have lots of rain or a long rainy spell the water is going to stand. Silty soil drains better, but a long wet spell and water from neighbor's property could still leave your yard excessively wet.

Once you know why the water is accumulating you can design a way to deal with the excess. A rain garden is simply a depression in the ground where excess water collects until it can soak in. Start digging a swale where water originates on your property and continue digging towards the lowest spot on your property. The swale does not need to be deep. In fact, a swale is a broad, shallow, grass-covered area that collects running water only in a heavy rain. https://a1guaranteedfoundationrepair.com/wp-content/uploads/2013/10/Swale-Drain.jpg You can dig up the grass, remove a layer of soil below that and reset your grass in the same spot. Some people fill a swale with rocks for a dry creek, but this is only necessary where the amount of water is already cutting a channel into the soil. Collect the dirt from your swale to use in shallow spots elsewhere in your yard.

When you get to the low spot dig a deeper, wider trench. Pile up the soil on the low side to make a berm. You can mix sand and garden soil with some of your native soil to put back into the trench. Put plant species that tolerate wet feet for a period in the low spot and on the berm. Here is one list of plants for the rain garden: http://raingardenalliance.org/planting/plantlist Yes, this is a lot of work, and you can't do anything until your yard has dried out some. However, when finished you will have a new bed of flowers and a less soggy yard.
