2013 Mosquito Reports

Post by maverick » Mon Apr 08, 2013 4:56 pm

1 - No mosquitoes or if there are some, but not biting yet
2 - Very light during the day, moderate at dawn and dusk
3 - Moderate during the day, heavy at dawn and dusk
4 - Heavy during the day, heavy at dawn and dusk
5 - Unbearable all day, no breaks, cannot eat outside of tent. If you stop, hundreds
will descend on you; when looking thru a camera viewfinder, you see more skeeters than
lake. If you slapped your arm, you'd smear blood from all the dead gorged bodies

I don't give out specific route information, my belief is that it takes away from the whole adventure spirit of a trip, if you need every inch planned out, you'll have to get that from someone else.

Laurel Lake-Kendrick Creek-Edyth Lake 5/10-5/13

Post by tomba » Wed May 15, 2013 10:29 pm

May 10-13 northwest Yosemite: Laurel Lk, Kendrick Ck, Edyth Lk, below Bearup Lk, Jack Main Cyn, Lk Vernon. Few mosquitoes in daytime at creek crossings and few other areas, including evenings/mornings at camps. Many mosquitoes evening/morning NE from Edith Lk at elevation about 7400 ft - just below first patches of snow.

Wind (which can keep mosquitoes down) was weak.

Cedar Grove: 0 (and none likely either - its already dry as a bone)
Paradise Valley: 0 (a few flies and butterflies in the afternoon, but too cold at night for skeeters)

The worst mosquitoes seem to be in a band from 7400-8200 feet.
A "4" at these locations:
Piute Lake
West Fork Cherry Creek Crossings
Piute Creek Crossing

At Deer Lake they were a 2, but were getting worse over the three days I was there.
