Notes

Sunny & chilly with strong winds chopping up the water creating whitecaps & waves. Icicles along the cliff from the spray. Couldn’t do exact measurement of depth but took a fairly accurate estimate based on many other times here. Lake levels not at extreme levels of some recent years but early yet and spring rains have yet to happen. No birds or wildlife around that we could see or hear.
