II. SITE DESCRIPTION AND OPERATIONS
2.1 Site Description
The Hartland diversion dam is located in Delta County on the Gunnison River (River
Mile 59.9) approximately 2 % miles (measured along the Gunnison River) upstream of U.S.
Highway 50 bridge at Delta Colorado (Figure 2.1). The diversion dam was constructed in 1881
and delivers an average of 40 cfs of water into the Hartland Ditch. The structure includes a 5
foot high by 300 foot wide dam spanning the entire river and a headgate and ditch on the north
bank. The structure, headgate and ditch are owned and operated by the Hartland Irrigation
Company (HIC).
The diversion dam is approximately 1 % miles north of Highway 50 and % miles
northeast of the City of Delta Golf Course. Access to the headgate on the northeast bank of
the river is obtained by following County Roads H40, 1600 Road, H75, 1675 Road and 1825
Drive, off of Highway 50. The diversion dam is located within a 30-foot wide easement on
private property.
2.2 Spill Channel Site Description
Approximately % of a mile downstream of the Hartland diversion dam on the Hartland
Ditch, there is an existing spill channel for returning excess flows from the Hartland Ditch back
to the Gunnison River (Figure 2.1). This analysis evaluates the feasibility of utilizing the
existing spill channel as a bypass channel to return fish from the Hartland Ditch back to the
Gunnison River. While other locations along the ditch may be suitable for a fish screen and
bypass channel, the intent is to utilize the spill channel and facilities that already exist.
