If you are planning on taking the boat out to Barr Lake, you ought to consider doing it pretty soon.
According to a Parks staff member the lake will only be accessible to boats (not including hand launched) for another 2 to 3 weeks.
She informed me they will be draining the lake to "conservation pool" so the head gate can be repaired.
Visibility is down to 1 ft due to algae bloom, and the temp. ranged from 73.5 early AM to 77.5 around noon.
