Check Dams

-Check dams are the type of dams that one rock dams fall in the category of
-Check dams and gabions are wire-wrapped dams that slow water which leads into a natural reservoir
-They slow the water, but do not cease it because the water is able to pass through it quite easily, just at a slower rate
-This allows the the water to seep into the soil much more easily
-So, the main purpose of check dams is to slow the water, so vegetation will grow and create a more scenic route in place of the natural drains caused by erosion
-One rock dams are the most easily check dams to build
-Even a large bed rock can create a scenic ephemeral spring, so imagine what a whole check dam could do
-And even though these dams help to slow water, they help dry creek beds be full once again
-Along with the more drainage into the soil, the slowly moving water leaves behind different nutrients that are key to the success of different plants
-The best place to put a check dam is in a dry creek bed or an arroyo so when the rain and floods come, the water is put to good use
