Permits:
- There is no specific county permit for a pond, but depending on the
size and location, certain permits may be required.
- If the area draining into the pond exceeds 240 acres you will need a
Kansas Division of Water Resources stream obstruction permit. For permit
forms call Topeka at 785-296-3717.
- If the pond capacity exceeds 50 acre-feet at top of dam elevation or
pond dam fill is 25 feet or higher then you will need a dam permit from
the Kansas Division of Water Resources.
- Do not place fill or regrade the land in a FEMA flood plain. Check the
flood insurance rate maps for your pond location. If in a flood plain
a Flood Plain Development Permit is required. Contact David Peel at Planning
at 913-715-2214.
- Work disturbing Waters of the United States will require a permit from
the U.S. Army Corps of Engineers. Call the Kansas City District at 816-983-3990
for more information.
Check for platted drainage easements or natural drainage areas, any pond
in these areas will require county approval. The specific requirements
are usually stated on the plat.
- Any federal, state or county permits will require submittal of engineered
drawings.
Pond Issues
Consider your
neighbor upstream.
Do not back water on your neighbors or road right-of-way. Your overflow
spillway needs to be at least 2 ft. lower than the low point at the property
line..
Consider your downstream
neighbor.
The dam needs to be upstream from the property line far enough that the
water flowing around the spillway gets back to the natural channel before
it gets to the downstream property line. This will be at least 50 ft.
from the property line, and probably much more. Some ponds leak, and your
downstream neighbor may complain about the seepage, you need to have a
plan to correct the seepage problem..
Other considerations:
Small ponds in large watersheds fill with silt relatively quickly, the
spillway is hard to maintain, and the dam may overtop in a large rainfall
event. As a rule of thumb, there should be 12 acres of drainage for each
surface acre of water.
Proper Construction:
Contact the Natural Resource Conservation Service for information about
proper pond construction.
