    RAINFALL  -
    Average rainfall of the region is 750 mm and highest rainfall experienced in Mahabaleshwar was 6090 mm & lowest rainfall experienced in Atpadi was 353 mm.
    On the basis of rainfall Region is divided into 3 zones.  
    1.  High Rainfall Zone                  -    Upto 1000 mm                -   Western part of area.
    2.  Assured Rainfall Zone             -     750 mm to 1000 mm     -   Middle part
    3.  Low Rainfall Zone (D.P.A.P.)  -     Less than 750 mm         -   Eastern part 
    Assured rainfall zone covers Sangli, Satara, Kolhapur and Pune districts and eastern part of Sangli, Satara, Pune & entire Solapur district is under D.P.A.P.area.
    619 Observation wells have been fixed in 263 Watersheds to monitor the groundwater level (Status) periodically and 220 piezometers have been constructed.

    GEOLOGY  -

    The region is covered by 99 percent hard rocks & 1 percent alluvium area. Major rock formation is basalt, in western part Kolhapur, Satara & Sangli districts laterite is noticed.  Radhanagari, Kagal, Bhudargad, Ajra, Gadhinglaj & Chandgad tahsils of Kolhapur districts granite kneiss is noticed.  In some parts of Satara district, bauxite is observed in small scale.

    GROUNDWATER STATUS  -
    Groundwater Status of Pune Region is mixed type, high rainfall in Sahyadri hill ranges, but due to steep slope and hard rock type more rain off and less recharge, hence poor in groundwater condition.  But major irrigation projects are constructed in Sahyadri ranges.  The D.P.A.P. area covers part of Sangli, Satara, Pune and entire Solapur district, where groundwater condition is moderate to poor, only Kolhapur district is rich in groundwater potential.  Due to excessive surface irrigation and poor drainage system, salinity problem is noticed in Sangli and Kolhapur district on the bank of Krishna river. 

    GROUNDWATER ASSESSMENT    -
    As per 6th Groundwater Assessment, out of 263 watersheds, 25 watersheds are over exploited and 8 watersheds are critical and 40 are semi critical.   Due to excessive draft, groundwater level is depleting in all over exploited and critical watersheds.

    SALIENT FEATURES  -  
    Pune region include Kolhapur, Sangli, Satara & Pune are developed districts in the region. Historical places like Shivneri, Purandar, Rajgad, Sinhgad, Pratapgad, Vishalgad & Panhalgad, etc. and Holy place like Dakshin Kashi (Kolhapur), Pandharpur, Nrusinhwadi, Alandi, Dehu, Jejuri, Morgaon, Ranjangaon, Theur, Lenyadri, Ozar, Sajjangad, Audumbar,etc.
