ABSTRACT:

This resource provides data related to the irrigation decision making for each county (agent) within the High Plains Aquifer Hydrologic Observatory Area from 1993 to 2020. The data is at a monthly scale, and includes monthly irrigation depth, monthly average prices of corn, wheat, soybean, sorghum and diesel, accumulated precipitation and average temperature from May to October.

ABSTRACT:

Non-point source pollution has been attributed as the cause of significant surface water quality concerns in the Great Lake Region. Over a hundred edge-of-field (EOF) runoff observational sites, which consist of hydrologic and meteorologic instruments are available at the edge of individual agricultural fields across the states in the region, are installed to measure and record runoff timing and magnitude. Conservation partners, such as Discovery Farms (Wisconsin and Minnesota), USGS, and USDA-ARS, provided the observational data. The identities of individual sites are removed to ensure anonymity. The selected model outputs of the National Water Model from the year 2004 - 2018 at the 250m x 250m grid are combined with the EOF measurements of the same location.
