present-day Mendua village. A third dam, located in present-day Bhopal, diverted more water from the smaller Kaliasot river into the Betwa dam reservoir. This man-made reservoir existed until 15th century, when Hoshang Shah emptied the lake by breaching two of the dams. Bhoja established the Bhoj Shala which was a centre for Sanskrit studies and a temple of Sarasvatī in present-day Dhar. According to folklore, the Bhopal city was established by and named after him ("Bhojpal"), but it is possible that the city derives its name from another king called Bhupala (or Bhupal). Literary works Bhoja was renowned as a scholar-king, and several books are attributed to him. Because these books cover an enormous range of topics, it is not certain if he actually wrote all these books or if he only commissioned these works, acting as a patron of their actual writers. But it is known that he was an expert on poetry, and the treatise Shringara-Prakasha was definitely authored by him. According to Ajada, who wrote a commentary titled Padaka-prakasha on Sarasvati-Kanthabharana, Bhoja wrote 84 books. The surviving works attributed to Bhoja include the following Sanskrit-language texts (IAST titles in bracket): Bhujabala-bhima (Bhujabalabhīma), a work on astrology Champu-Ramayana or Bhoja-Champu (Campūrāmāyaṇa), a re-telling of the Ramayana in mixture of prose and poetry, which characterises the champu genre. The first five kandas (chapters) are attributed to Bhoja. The sixth and seventh chapters were completed by Lakshmana and Venkatadhvarin respectively. Charucharya (Cārucārya), a treatise on personal hygiene Govinda-vilasa, poem Nama-Malika, a compiled treatise on lexicography Raja-Martaṅda (Rājamārtanḍa) or Patanjali-Yogasutra-Bhashya, a major commentary on the Yoga Sutras of Patanjali; includes an explanation of various forms of meditations Raja-Mriganka-Karana (Rājamrigankakaraṅa), a treatise on chemistry, especially dealing with the extraction of metals from ores, and production of various drugs.

It details construction of buildings, forts, temples, idols of deities and mechanical devices including a so-called flying machine or glider. Sarasvati-Kanthabharana (Sarasvatīkaṇṭhabharaṇa), a treatise on Sanskrit grammar for poetic and rhetorical compositions. Most of it is a compilation of works by other writers.
