Acreage having the problem is the total acreage subject to the watershed 

 project problem to which the estimate applies even though it may have been 

 met already by individual or project action. For example, the acreage of 

 land with a drainage problem includes all land subject to problems of excess 

 water even though it may have an adequate system of drainage. The estimates 

 for this item were provided by the Soil Conservation Service for non-federal 

 lands and by administering Federal agencies for public land.
