2020 Mid Shore fishing was quite extended and trends really picked up after a significant bump in flow around May 1st:
Unfortunately just not quite enough data to draw strong conclusions about 2020 Mid Shore other than the expected increase in catch post-MMT:
Mid shore All Time: Mid Shore has always been a bit of an enigma, but a clearer picture continues to emerge:
The Upper Shore flirted with MMT around the 17th of April in which you can see an unmistakable increase in catch trend. The lack of reports and data between the 20th and May 1st created a few issues for analysis:
Upper Shore Weekly: Same general pattern noted here with increases in catch post-MMT:
Each peak from left to right beginning with the large April 16th - April 22nd peak represent historical creel peak for Lower, Mid and Upper Shore respectively. The early peak the week of April 2nd through April 8th was a strong and early run year that is still evident in the chart. The Upper Shore peak is not quite as defined due to low late-season reporting from that region, but it is beginning to clarify.
It is unlikely the average time spent in stream holds exactly true for all returning fish within all North Shore streams. Many of our streams are smaller short-run streams which tend to warm quickly, and can approach thermal stress thresholds far earlier than the larger ones. What we typically see in the creel data is that by the time average stream temps exceed 54-58°F, things appear to start wrapping up. We also have conclusive evidence of steelhead, largely tagged males, traveling great distances (+/- 60 miles!) in a short amount of time, then moving in and out of different rivers during the same run year. We're not sure how long those fish remain in a given river, but since they are trapped, tagged and subsequently reported from a different river all-together in the same year, they probably aren't spending a ton of time in any one stream.

MNST extends our sincere thanks and gratitude to all of the hard-working folks at Minnesota DNR Fisheries. Your dedication and commitment to the management and preservation of natural resources in the State of Minnesota does not go unnoticed and is greatly appreciated. Oh, and all those technical papers and reports you put out, we actually read them. Cheers!
Best of luck, good fishing and we'll see you on the water-
