Indonesia's only freshwater dolphin is the facultative Irrawaddy river dolphin Orcaella brevirostris in the Mahakam River in East Kalimantan, Borneo. To clarify the status of this Critically Endangered subpopulation we carried out a series of surveys from early 1999 until mid 2002 on abundance, habitat use, population dynamics and threats. Our estimates of total population size were 33–55 dolphins (95% confidence limits 31–76) based on direct counts, strip-transect analysis, and Petersen and… 
Estimates of abundance and apparent survival of coastal dolphins in Port Essington harbour, Northern Territory, Australia
TLDR
The values derived here provide some of the only estimates of local population size for these species across monsoonal northern Australia, and the low apparent survival probabilities indicated that many individuals may move at scales larger than the study area.
Conservation ecology and phylogenetics of the Indus River dolphin (Platanista gangetica minor)
The historical range of the Indus River dolphin has declined by 80% since the 19th century and has been fragmented into 17 river sections by construction of irrigation barrages. Dolphin sighting and
Seasonal movements of river dolphins (Inia geoffrensis) in a protected Amazonian floodplain
Deliberate killing for use as bait in a regional catfish (Calophysus macropterus) fishery is the primary threat affecting the survival of the Amazon river dolphin, or boto (Inia geoffrensis).

TLDR
Understanding the preferred habitat and identifying hotspots of freshwater-dependent cetaceans in the Sundarbans is the first step of a planning process for the potential establishment of a network of protected waterways for these threatened species.
Abundance and Prey Availability Assessment of Ganges River Dolphin (Platanista gangetica gangetica) in a Stretch of Upper Ganges River, India
TLDR
Dolphin density showed a significant positive relationship with density of Reba fish (Cirrhinus reba) and Baam fish (Mastacembelus armatus) and also with water depth, indicating their preference for deep water pools.
