Maps and Plans

IMPORTANT: Maps and Plans are to be filled only when Co-ordinates for all points of diversion and reservoirs are required. If a dam is to be built, co-ordinates should be provided to the point where the outlet pipe intersects the center line of the dam.

To Fill Maps and Plans:

Enter Name of the Reservoir.
Enter Temporary Filing Number.
Enter Freeboard above spillway.
Enter Top width in feet.
Enter Top of Dam elevation in feet.
Enter High water line elevation in feet.
Enter Upstream slope.
Enter Top height in feet.
Enter downstream slope.
Enter Outlet pipe diameter in inch.
Enter Dm (Maximum Water depth minus freeboard).
Enter D1 (Water Depth below Outlet).
Enter Area at High Water Line (HWL).
Enter Area at elevation of outlet.
Select type of valve from the drop-down list.
Enter Total Capacity.

NOTE: Total Capacity = Area at HWLxDm/3.

Enter Inactive Capacity.

NOTE: Inactive Capacity = Area at elevation of outlet x D1 /3.

Enter Active Capacity .

NOTE: Active Capacity = Total Capacity-Inactive Capacity.

Enter Length.

NOTE: Measure length as a straight line (at HWL) from the dam to the most remote point.

Enter Width.

NOTE: Measure width at HWL along dam.

Enter Average Depth.

NOTE: Average Depth = Total Capacity/Area at HWL.

Enter Calculated Area’

Select Spillway Shape’
Enter Wetted Perimeter
Enter Area
Enter Hydraulic Radius
Enter Energy loss per foot of channel length
Enter Manning Coefficient of Roughness
Enter Cross-Sectional Average Velocity
Enter Discharge
Enter Submitted Date
Enter Accepted Date

Note: Accepted must be equal to or later than the 'Submitted' date, unless the 'Submitted' date is in blank.

Enter Adjudicated

Note: Adjudicated must be equal to or later than the 'Submitted' and 'Accepted' dates, unless they are in blank. Error messages will be provided if these rules are violated.

Check I declare, under penalties of perjury, that I have examined this application and the information contained herein, and to the best of my knowledge and belief it is true, correct, and complete, and that the location of the proposed facility is accurately shown on an aerial photograph or United States Geological Survey quadrangle map accompanying this application or delineated in this application.

IMPORTANT: You will be required to complete and mail a Form SW3-A or upload the form with a location map, plan view of the dam site, and a profile of the dam site. You can copy the provided Location Map, Details of Dam Sketch, Capacity, and Body of Reservoir questions/answers into your Form SW3-A.

To Fill Plan View and Profile:

You have the option to enter the pit capacity in any one of the following ways.

Select Directly

Note: The calculations will be provided by the applicant in the Area/Plan View and Profile drawing, i.e., an Area/Capacity Table.

- Enter Calculated surface area in acres
Enter capacity in acre-feet
Select Computed by e-Permit using input measurements

Note: If you selected Computed by e-permit, System will calculate capacity based on inputs.

Select any one of the following computation methods.

- Pits with an irregular shapes
  Pits with an irregular shapes:
  - Enter Calculated surface area in acres
  - Enter Depth(D) in foot
  - Enter Top Area(T) in square feet
  - Enter Bottom Area(B) in square feet
  - Enter Capacity in acre-feet
  Note: Capacity will be calculated by formula (D/3*[B+T+sqrt(B*T)])/43,560
- Pit with a rectangular shape and flat bottom
  Pit with a rectangular shape and flat bottom:
  - Enter Calculated surface area in acres
  - Enter Depth(D) in foot
  - Enter Top Area(T) in square feet
  - Enter Bottom Area(B) in square feet
  - Enter Average Area in square feet
  - Enter Capacity in acre-feet
  Note: Capacity will be calculated by formula
  
  Capacity = (D / 6 * [T + B + 4 * A])/43,560
- Alternate method selected by applicant
  Alternate method selected by applicant:
  - Enter Calculated surface area in acres
  - Enter Depth(D) in foot
  - Enter Top Area(T) in square feet
  - Enter Bottom Area(B) in square feet
  - Enter Capacity in acre-feet

Check I declare, under penalties of perjury, that I have examined this application and the information contained herein, and to the best of my knowledge and belief it is true, correct, and complete, and that the location of the proposed facility is accurately shown on an aerial photograph or United States Geological Survey quadrangle map accompanying this application or delineated in this application.
