Bruce Ajari | Fall fishing season starting slowly
October 14, 2010
A trip this past weekend to one of my annual fall fishing haunts, Frenchman Reservoir northeast of Truckee, was better than it was two weeks ago, but still nowhere like it typically is this time of year. So, what seems to be the problem with the early fall fishing this year?It can probably be explained by the unseasonably warm weather that we experienced earlier this month. Have you noticed that the fall colors are much slower to change this year?The lack of those cooler temperatures has caused the water temperature to be unusually high in our lakes for this time of year. Two weeks ago the surface water temperature was 61 degrees. That is unheard of for the last week in September. So last week with the cooler evening and the recent rains, you would figure that the water temperature would be much cooler. Well, it was 60 degrees when we got there this time. It was 61 degrees later in the day.These warm temperatures can make fish difficult to locate. While 61 degrees is still within a troutandamp;#8217;s good temperature range, it is on the warmer side. Two weeks ago the afternoon temperatures were reaching the 65-degree range. At this temperature fish will seek deeper water because of the lack of dissolved oxygen.Typically, water temperatures for this time of fall are in the mid- to upper-50-degree range and the fish are all over the shallows. While fish can still be found in the shallows, the angler must look for areas that fish will actively feed. First and foremost a fly fisher in a lake environment should be looking for established weed beds.This was the formula that worked for us this past week. After spending a pretty tough morning in one location, we moved to another one and found the established weed beds in an area that also had some springs. In manmade reservoirs, weed beds that were there one year may not be there the next due to the amount of water, so an angler needs to be aware of this and be willing to move.After the move we were very successful since the fish seem to be concentrated in the area in which we were fishing and actively feeding. So, be sure and look for spots that will give you the best chance of success in manmade reservoirs.andamp;#8212; Bruce Ajari is a Truckee resident and regular fishing columnist for the Sierra Sun and other area newspapers.
