Good guess. That may be a problem in Canada.
But, no I'm talking about ~10% of
the mule deer drowning attempting to swim the reservoir,
twice a year. This according to a local (Fresno area)
EIS. Spillway elev 5713. A 1000 acre (small) reservoir
with a 300-foot tall dam.
It's smack dab on a major migration corridor. AND
population center, AND fawning area. And Fish & Wildlife
say the population is already too low, way down.
