 |
The Groundwater Management District Association (GMDA) is
composed of local groundwater management districts in several Midwestern and Southern
states. At our Annual meeting we have presentations from noted experts in the fields of
hydrogeology, geology, flow meters and different management strategies. This provides us
with a forum to exchange ideas on the different approaches taken by other States. For
example, the primary issue in Kansas, Colorado and Texas is groundwater quantity,
while in Nebraska it is groundwater quality and quantity. In Mississippi and
Florida,
Districts are responsible for the joint management of surface and
ground water and subsidence is the major issue in Louisiana and
parts of Texas. Some of the Districts have developed
unique projects in education and management to preserve our groundwater resources for
future generations. |

Steel Tapes to Measure Ground Water Levels: |
| The
Districts use steel tapes to measure groundwater levels in wells
as part of our monitoring networks. Steel tapes with the
raised markings are preferred due to their ridge construction,
ability to retain chalk and give an accurate reading.
Steel tapes are still available from Cooper Handtools (www.cooperhandtools.com),
but these do not have the raised markings along their entire
length. |
| Some Districts are now using fiberglass tapes as an
alternative. Click on the link "Measuring
Groundwater Levels" for more information, which is also located on the
"Association Update" page. |
