What is it about?
We present a methodology for estimating the ability of drained wetland depressions to store runoff in farmed watersheds at multiple spatial scales, and show that in central and north-central Iowa these landscape features have insufficient storage capacity to significantly alter regional and sub-regional flood events.

Why is it important?
Our study addresses a long-posed question about the effects of depressional wetland drainage on flooding in Iowa.
Perspectives
This article grew out of a unique collaborative effort to map and characterize landscape depressional features on a regional scale. The findings of the original research effort and this article have led to additional exciting insights into the unique hydrology of depression-dominated landscapes.
