There are a few more bats at Woodard Bay than when the lake draining occurred, but the effect of the incident probably won't be obvious until next year, when we see how many bats made it through the winter, and return to the maternity colonies.

At Woodard Bay, there was a big drop in the number of bats flying out of the pier, but it gradually increased as the young started flying. What we don't know is how many young back at the pier roost were waiting for milk that never arrived, and may have perished--they'd drop in to the water, so we wouldn't be able to document this as we can at roosts over land.
