Number Lakes Thread As for the Number Lakes - they are as busy as ever. Tons of people in the prime season. The fire has not seemed to diminish the traffic. There are still 14 permits each day for Lake One. And, they are usually all taken.
Many of the northern sites in Lakes One, Two and half of Three were either not affected or had water dumped on them during the fire and the sites are Ok. There does not seem to be a change in the wind - if it blows, it blows. Fishing seems to be the same as it has been for years ( b/4 the fire).
The sites are pretty burned from the south half of Lake Three, thru main body of Four, south 3/4 of Hudson and the southern half of Insula.
The north finger of Hudson and likewise Lake Four are not burned. Those sites go fast.
