Water-right lineage

This timeline puts WDID 0400543’s decreed rights (South Side Ditch) — the same rights as the portfolio above — in chronological order by appropriation date (oldest first), grouped by decade. It reflects DWR’s current net-amounts tabulation, not a complete decree history: intermediate decrees, changes, and abandonment proceedings exist only in the underlying court case files. It is not a title opinion and not a complete chain of title.

17 additional rights recorded only as alternate-point/exchange (APEX) net amounts are not included in this timeline. 5 rights shown also carry APEX amounts that are not displayed.

Irrigated acreage history

These snapshots track state-mapped parcel linkage to the listed structures; they do not measure the company's operations or status.

• Grass Pasture
• Alfalfa
• Dry Beans
• Corn
• Small Grains

Source: CDSS Division 1 Irrigated Lands snapshots (1956, 1976, 1987, 1997, 2001, 2005, 2010, 2015, 2020). These parcels are the ones the state links to WDID 0400543. The parcels are mapped by the State of Colorado, not by the company and not by DitchBook. The state's mapping for this company includes parcels the state maps to this company's structures together with other structures; parcels the state maps to this company's structures alone. Where parcels are shared with other structures or linked to a well, the acres shown are not all served by this company's ditch alone. How this page is built.

Footprint: state-mapped irrigated parcels for WDID 0400543, 2020 snapshot, from CDSS Irrigated Lands. The dashed outline is a service-area layer (vintage 2005) shown for context only — it is not used for any figure on this page; source: CDSS Div1_Canals package, Div1_Ditch_Service_Area_2005. The solid line is this company's ditch/canal alignment — USGS National Hydrography Dataset (hydro.nationalmap.gov/arcgis/rest/services/nhd/MapServer/6), name-matched against DWR structure/company name and reviewed by DitchBook as of 2026-08-07 — mapping-grade, not a survey. Shown for 1 of 1 reviewed structure. The second solid line is Big Thompson River, this company's published water source, matched the same way.
