boaters, who claim it is difficult for anyone but a local resident closely watching the gauges to plan trips in advance on the river. The San Juan Citizens' Alliance has worked to start a dialogue between Dolores River stakeholders in the hopes of shifting release policy to one that allows for greater, planned releases.
588:, its main tributary, from the east. (Incidentally, the Dolores and San Miguel have their headwaters to either side of Lizard Head Pass.) Due to diversions on the main stem, the San Miguel is typically the same size as the Dolores if not larger, providing most of the flow below the confluence in dry years. 761:
The dam's construction allowed local farmers to extend the irrigation season through September, whereas natural river flows would have been insufficient by July or August. While the dam has reduced and sometimes completely halted spring peak flows in the lower Dolores, it provides supplemental flows

Releases from McPhee Dam are a controversial topic. Currently, the Bureau of Reclamation operates McPhee on a "fill, then spill" policy, where the dam is filled first, and only in high water years when inflows exceed the reservoir capacity are larger flows released. This fact aggrieves recreational

650:, at the entrance to Paradox Valley (above the San Miguel confluence) the effect of the flow reductions is more obvious, with an average of 504 cubic feet per second (14.3 m/s) before September 1984 as compared to 240 cubic feet per second (6.8 m/s) between October 1984 and May 2014. 762:
