Otero County Water Intelligence Brief

June 8, 2026 | Arkansas River Basin | Free-Tier Edition

Situation Summary

Otero County enters mid-June 2026 facing one of the most constrained irrigation seasons on record, driven by an anomalous early-season melt in the upper Arkansas headwaters and a critically low Fryingpan-Arkansas Project imported water forecast for the year. Upper Arkansas SNOTEL stations have fully melted out, signaling that snowmelt-driven inflows to Pueblo Reservoir are tapering toward base flow conditions with the core of the irrigation season still ahead. Reservoir storage figures, 7-day forecast details, and canal delivery outlooks are available in the full brief.

Snowpack Conditions

The two SNOTEL stations monitoring the upper Arkansas headwaters both report exhausted snowpack as of June 7, 2026.

Brumley (Lake County) recorded a snow water equivalent (SWE) of 0.8 inches with a snow depth of 0.0 inches. The residual SWE reading with zero snow depth indicates the sensor is capturing late-season trace moisture, not meaningful snowpack. No percent-of-median figure is reported for this date, meaning the historical median SWE for this point in the calendar is also near zero — this station is at its normal seasonal condition for early June. However, the critical signal for 2026 is not today's reading but *when* meltout occurred: Brumley melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by the anomalous March heat wave that accelerated snowmelt across the Mountain West.

Saint Elmo (Chaffee County) recorded 0.0 inches SWE and 0.0 inches snow depth. No percent-of-median is shown, consistent with normal seasonal conditions for this calendar date. Like Brumley, the meaningful signal here is early meltout timing — Saint Elmo also melted out well ahead of the historical median.

Taken together, both headwater stations confirm that the snowmelt pulse for the 2026 season has ended. Turquoise Lake, Twin Lakes, and ultimately Pueblo Reservoir can no longer expect meaningful snowmelt contributions from the upper Arkansas basin. Canal companies and irrigators should treat the snowpack signal as exhausted for planning purposes.

Streamflow Conditions

Three USGS gauges monitor Arkansas basin flows relevant to Otero County, with mixed data availability as of June 8, 2026.

Apishapa River near Fowler, CO is reporting an active flow of 2 cfs, with a rising trend. The Apishapa is a tributary to the Arkansas and its flow, while modest, provides some indication of localized runoff or return flow contributions to the lower basin system.

Arkansas River at La Junta, CO — the primary supply indicator for Otero County canal deliveries — has no recent flow data available as of this brief. La Junta (USGS 07123000) is the key gauge for understanding mainstem Arkansas availability reaching the lower valley. Users should check USGS Water Information System directly for the most current readings.

Arkansas River near Rocky Ford, CO also shows no recent flow data available. The Rocky Ford gauge (USGS 07120500) is strategically important because it captures flows *after* Fort Lyon Canal diversions — when compared against La Junta readings, the difference between the two gauges provides a rough indication of active Fort Lyon diversions. The absence of current data from both gauges limits that comparison today. Fort Lyon Canal Company, Catlin Canal Company, and Holbrook Irrigation District members should contact their respective canal offices directly for current delivery status.
