During 2012, there were so many people fishing at Chesterfield Reservoir that the irrigation company couldn't get past the vehicles parked on the dam to get to their pump house. One instance involved the irrigation company accidentally bumping a private vehicle parked on the dam and causing some damage while trying to get to their pump house. The private individual wanted to sue the irrigation company. This caused the irrigation company to work with Fish and Game to come up with a solution that would not close the reservoir to all public fishing. The gate was put up as a compromise. There is still foot access to the dam for fishing, there will be no vehicle access for the public across the dam.
