Notes

Mostly sunny with some clouds and no rain in past 24 hrs. Lots of cormorants in water.

Location description
Reading taken from a small municipal dock and launch ramp near the Waupoos Marina. A good place to dive off on a warm day. But the water weeds now almost reach the surface. Much larger that 15 years ago. Sunny day with not much wave action
