Leon River at Hasse — common questions
3 questions
How do releases from Proctor Lake affect this stretch?
Directly and fast. When the dam generates, flow here can climb by an order of magnitude within the hour, with no rain anywhere in the basin. That sudden release is the real hazard on a tailwater. The pool level is on lakelvl.com, linked below.
Is Leon River at Hasse high or low for this time of year?
The USGS median flow for late September here is 18 CFS, from 48 years of record (1963–2026). Today sits inside the middle half of those years, at 141% of the median. The comparison is what makes the raw number mean anything: the same reading is a drought on one river and a flood on another.
