The Sacramento Bee reports state and federal wildlife officials have announced a plan to move hatchery-raised salmon by tanker trucks should the river and its tributaries prove inhospitable for the fish.
Officials fear the rivers could become too shallow and warm to sustain salmon trying to migrate on their own.
They're keeping an eye on conditions and will be ready to implement the plan next month, barring heavy rains.
Salmon from the Coleman National Fish Hatchery on Battle Creek, a tributary of the Sacramento River, are usually released in April and May.
The trucking plan is similar to one carried out in the drought of 1991-92.
Sacramento city council voted in favor of a proposal that makes some drought watering restrictions permanent.
Tuesday marks the start of a shortened commercial salmon fishing season in the waters off San Francisco. A smaller salmon population is one effect of the drought that could persist for years.

The Central Sierra Nevada snowpack this year is larger than the previous four years combined, according to new data from NASA.
