Crews are suspending their search for a two-year-old boy who reportedly fell off a boat Saturday into Carter Lake in Larimer County.
Sheriff's office spokeswoman Eloise Campanella says recovery operations are expected to resume Tuesday, when technical sonar equipment will arrive from out of state.
Sunday, divers used cameras, global positioning systems and sonar equipment to search depths up to 130 feet. Campanella says beyond that, divers had no visibility.
Park rangers are expected to stay in the area Sunday night and Monday.
The boy was reported missing to the sheriff's office about eight p.m. Saturday. The toddler was in a ski boat with two adults, one of whom was his father from Longmont, and another three-year-old child.
His name hasn't been released.
