Water facts
No live USGS water-temp or pool gauge on the reservoir (the Chamberlain and Big Bend gages report elevation only), so the bite score uses the seasonal baseline. Access at Chamberlain (American Creek), North Point, Platte Creek and Snake Creek recreation areas. Walleye 15 in minimum year-round except July-August; only one fish 20 in or longer per daily limit. A seasonal closed area (Dec 1-Apr 30) exists between the railroad and I-90 bridges at Chamberlain. Verify on the SDGFP Missouri River regulations page.
