Water Quality Maps for Nitrate-Nitrogen in a Minnesota Agricultural Watershed

350.2 KB of water quality data collected from ditches and streams in the High Island Creek watershed in Minnesota. Data were gathered from an inflatable raft to create high spatial resolution maps, interpreted to characterize watershed influences on nitrogen transport or removal. The dataset was created by BRENT DALZELL and supports a published manuscript in Biogeochemistry.

Use Cases

• Analyzing spatial patterns of nitrate-nitrogen concentrations based on high-resolution water quality maps.
• Investigating temporal stability of nutrient export patterns in contrasting agricultural stream reaches.
• Identifying control points for nitrogen transport or removal based on surface flow-path sampling data.
• Informing the placement of fixed-site monitoring stations in homogenous landscapes using spatial dependence data.

Strengths

• Data has high spatial resolution, collected from an inflatable raft to create water quality maps.
• Dataset is 350.2 KB in size, making it quick to download and process.
• Supports peer-reviewed research published in the journal Biogeochemistry.
• Released under a permissive CC0-1.0 license for broad reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data scope is limited to specific portions of a single watershed (High Island Creek, Minnesota).
