Temperatures in the Bemidji area dropped below freezing on Election Night and have stayed below freezing since. An early November snow was enough to cover the ground and make it easier for deer hunters to see fresh sign in the woods. The snow also makes it easier to see the brown colored deer moving through the woods against a white background. The extended forecast for the Bemidji area is predicting more cold weather for the immediate future, with overnight lows dipping into single digits some nights.
The 2018 Minnesota Rifle Deer Season opened Saturday. Experts at the Minnesota Department of Natural Resources are estimating the total deer harvest in 2018 will be at least 10 percent higher than the approximately 200,000 animals harvested in 2017. The forecast for the Bemidji area includes a chance of rain or snow for most of the first week of the deer season, but the temperatures will be mild, in the 30s and 40s most days. This should allow hunters to sit in their stands longer without getting cold.
The Minnesota Rifle Deer Season opens on Saturday and goes until Nov. 18 for areas in the 100 series, which includes most of the Bemidji area to the north and east. Most anglers put their boats away by the time the rifle deer season opens, because most lakes will likely have shoreline ice by the time deer season is done. A few anglers will keep fishing until they can't get their boats in the lakes any longer. An ideal deer opener for some people would be to get their deer in the morning and still have time to catch a limit of crappies in the afternoon.
The small ponds and swamps are freezing and some of the shallow lakes are starting to form skim ice along the shoreline. Unless there is a drastic change in the weather, it looks like an early winter this year. Things can still change, it looked like a late winter during most of September when it was so hot. Bemidji and the rest of northern Minnesota are known for drastic weather changes, so it is possible to still have some warm weather this year, but keep your long underwear handy just in case.
Another cold week with rain and snow has sped up the cooling process on the lakes and has many of the deep lakes beginning to turn over. Anglers can see the dead algae floating on the surface of the lakes in the mornings, before the wind has a chance to mix the algae back into the water. Algae dies quickly when the water temperatures drop and will remain at low levels during the winter. Algae will spike again in the spring after ice-out when water temperatures begin to rise.
Cold and wet would accurately describe this past week in the Bemidji area. The fall colors are near their peak, with the leaves getting blown and rained off trees at a fast rate. After a warm first three weeks in September, the temperatures ironically dropped dramatically once fall officially arrived on the calendar. The fish had been staging to make their move into deeper water as soon as the thermocline disappears in the lakes. Many lakes still had a visible thermocline early in the week, but by the end of the week, the thermocline was gone from most lakes.
October is on the doorstep as another month has nearly gone by. The first frost of the season was this week, so those troubled by allergies should be getting a little relief soon. The leaves have started to change color, with this week and next weekend close to the peak viewing in most of Northern Minnesota. The wind and the rain will knock the leaves off the trees fast, so sooner is better for those who want to see the fall colors near their peak.
The fall cool down resumed in earnest this past week, after what was probably one last fling with the upper 70s through last weekend. Surface water temperatures in many lakes rose back to around 68 degrees after a string of unseasonably warm days last week. Surface water temperatures have been dropping almost one degree per day when the temperatures stay in the 50s for the highs and 40s for the lows. The slowly declining temperatures may be here to stay this time, with the first frost of the fall likely to happen soon.
The warm fall weather continued this past week, with surface water temperatures holding in the mid-60s, with some lakes warming slightly back into the upper 60s. A slow but steady cool down prolongs the best fishing in the fall, with the best fishing still ahead of us in the Bemidji area. A sudden cold snap would quicken the process of cooling down the lakes, but the fish don't like anything to change too fast, or they usually respond negatively for a period of time until the conditions stabilize.
The fall cool down continues as surface water temperatures in the lakes drop to the mid-60s. Fall fishing patterns can be slow to develop after a long hot summer, but by the time surface temperatures cool down to about 65 degrees, the fish have already started to move and get more active. It is the same thing when fish get more active in the spring as the water warms as it is in the fall when fish get more active as temperatures cool in the fall going through the same temperature range.
