With the income tax deductions for wetland conversion adoption of the "no net loss" goal, efforts to conserve (Heimlich and Langner, 1986; Heimlich, 1994). and restore wetlands accelerated. Drainage and Flood Control The Era of Wetland Exploitation Federal involvement in drainage programs dates back In the earliest stages of settlement, farmers bypassed to 1902 when the Bureau of Reclamation was estab- wetlands in favor of dry land with good water and lished to develop irrigation in the West.

Farmers using Bureau irrigation encountered drainage problems By a strange quirk of fate those who blazed while developing irrigation systems in such areas as the first trails and developed the first farms in the Newlands Project in Nevada, the Modesto Iowa found [...] that their timber-prairie farms Irrigation District in California, the Mesilla Valley of near the rivers were often less valuable than New Mexico, and the marsh lands of Western Oregon. the farms developed by those who came much Large-scale agricultural drainage solved irrigation later and took the land they had avoided.
